Consumers warned about possible drug mix-up - CNN
Novartis Consumer Health Inc. has been compelled to recall batches of of strong prescription painkillers ending up in bottles of these OTC drugs. to call the Consumer Relationship Center at or for more. And consumers who have select bottles of Excedrin, Bufferin, NoDoz and Gas-X, produced by Novartis, are being told to discard or return the products in a voluntary recall that "This could result in an incorrect pill ending up in the bottle of Novartis Consumer Relationship Center or try to obtain a refund. The Excedrin recall was attributed by Novartis to problems at its Nebraska and to begin restocking pharmacy shelves by the end of the year.
Therefore, we focus on relevant projects that focus on representing or adjusting our perception of time. For example Breakaway — a desk sculpture that nudges users to take a break when they have been sitting too long Jafarinaimi, et al. Nimio Brewer, Williams, Dourish is an example of a tangible device that represents user activity using different light hues, and Tea Place Lee, et al.
The Durr watch is a device which tries to present the objective perception of time using a method different than clock hands: The Durr watch vibrates every five minutes of objective time. However, the Durr watch was a prototype and the idea was put on hold. He explored how this would affect users. Slow Dance is a Kickstarter project in which Jeff Lieberman tries to alter the perception of time using strobe lights. At 80Hz, a strobing light is perceived by human eyes as constant, however, when a moving object is placed within the range of the light, the object will appear to move slower as if it were in slow motion.
We decided to exploit this behavior in our project to make objects seem slower or faster than they appear to be moving at.

The most recent hour is the clearest, and the oldest one is the least visible. The effect that it creates is that a person should focus on the most recent hours rather than the oldest ones. As night time comes, the watch face becomes black and vice versa in daytime it becomes light Circadian clock: There were 3 main guidelines for our design: This way, we are augmenting an already acceptable and used product. Extra hand and strobe light: We would add an extra hand to the clock and the speed of this extra hand would represent our subjective time.
As time slows down for a person, the extra hand would go in slow motion, and vice versa. We decided to use the strobe light effect here as it allows us to change the perception of an object moving at a constant rate. Using strobe lights, we could show the hand completely frozen or moving in slow motion forward and backward or quickly jumping between positions again, forward and backward.
People can perceive time as slowed down for different reasons, e. Similarly, time may speed up when we are happy or focused. To disambiguate the different states during which time slows down or speeds up, we decided to use colors to guide the users. For example, when a user is sad, the extra hand would slow down, but the clock would be purple colored. Whereas when the user is afraid, the extra hand would still slow down, but the clock would be blue colored.
The initial concept design accounted for the aforementioned guidelines. The EMIT timepiece would consist of a set of mechanical hands that present objective time in the innermost layer. When the clock is not enabled by a user in the near vicinity, the time perception and emotional cues are inactive.
It is important to note that emotional and time perceptual displays are independent. Although mechanical control of a servo or stepper motor would allow use to implement a traditional clock hand effect of which we could adjust speed and direction, we include some advantages of choosing strobe lights over a more traditional, mechanical approach: A mechanical hand would always be there.
Even if the hand was disabled, it would be constantly visible to the user. In our design, we strived to create a device for which the user could opt in or out for different markers. For instance, a user might not want to display time perception at some point during their day, in which case a mechanical display of time perception is unnecessary. With the strobe lights, the mechanical time perception hand is spinning so fast that it is practically invisible to the naked eye.
Whenever the user wants to opt out of the time perception display, the strobe lights can be turned off, making the time perception hand invisible. A mechanical hand would only allow use to display increases in speed and direction through the usage of the EMIT system.
In the case of a strobe display, different frequencies can be used to achieve effects that would normally be impossible for a traditional mechanical hand. For instance, strobing at multiples of the rotating frequency of the motor can make it seems like there are multiple hands.
Moreover, other effects can be implemented to create more complex interactions. A mechanical hand would only support the display for the perception of a single user.
In order to show the perception of more users, multiple hands would need to be included in the system to show differing perceptions of time. Different sets of strobe lights can be programmed to strobe at different frequencies to create the illusion of multiple hands moving at different speeds, which would allow multiple users to concurrently interact with the system. Studies Chebat, et al.
Hanus, Kang, Ricker N. For this, strobe light controls might prove a suitable alternative to subliminally alter a user who is looking at the clock. The model is available online in the following link: Rotation motor to spin the extra hand This component will consist of a simple switch that will turn on and off the motor.
In a future iteration, the switch will be controlled by a microcontroller that detects the presence in order to conserve energy. Strobe lights to create the strobe effect This component consists of a simple transistor which controls whether a LED strip is powered on or off.

In future iterations this component will be improved to give more power to the LED strip. Implementation Failure-First Prototype V1 The biggest concern we had about the clock was about the strobe effect. This was because we had never used strobe lights before and we were not sure how to create the effect. We figured out that there were two big considerations in strobe effect: Rotational motor Consistent strobe light frequency and brightness Initially, we used servo motors as a rotational motor because they allow control over the motors rotations.
But servo motors have low rotations per minute RPMand even at the max speed, the rotating hand was visible to the naked eye and slow. The constraint with DC motor is that DC motors do not allow fine control over the motor speed.
This allowed us to test the motor and strobe light effect without having to make our own strobe effect and thus, made sure that our tests were independent of any errors in our strobe lights. We ended up putting a motor with a Lego brick to simulate the rotating hand in a holder. We placed this system inside a cardboard box. However, the LEDs were not bright enough while strobing and we decided that our next step was to figure out a brighter light source to create the strobe effect.
Lessons learned from the first motor and iPhone strobe light test: The motor and the hand needed to be relatively stable. Extra vibrations in either the motor or the hand prevented us from creating a smooth slow motion strobe effect.
Category Archives: 2017 Final Projects
The rotating hand had to be balanced about the center. If most of the weight was just on one side, the rotational frequency varied slightly, but that was enough to break the smooth frozen effect of the strobe light.
To freeze motion using strobe light, we need the strobe frequency to be an integer multiple of the rotational frequency. If the hand was not balanced, the rotational frequency varied and thus, it was difficult to freeze motion using the strobe light.
Pick brighter strobe lights Stabilize the motor and rotating hand Our initial choice for a strobe light was this: This was a very bright light lumens and we were able to control the frequency to strobe the light, and when we were testing it in front of the hand, it worked really well, i.
However, when we placed it in front of the hand inside the clock, it needed to be at least 7 inches away from the hand to illuminate completely the portion of the hand that was sticking out behind the light and henceforth be visible to the user.
Therefore, we decided to abandon this light because of its form factor, limited illumination, and small strobing frequency range. Our next choice was these LED strips: These LEDs turned out to be very bright and the flexibility of the strip allowed us to wrap the lights around the edges of the clock facing the LEDs inwards so that they were focused on the rotating hand.
We were able to strobe the lights at a very wide range of frequencies. Status lights We used Neopixel lights to show the emotion colors. We used a translucent white sticker to diffuse the light from the Neopixels. Clock We used real clock hands: We stuck the clock mechanism behind the translucent screen so that only the clock hands were visible and the clock system itself was hidden. We use this board to control the status and strobe lights using commands from the Android phone.
Circuits We had two main goals for this prototype: Replace the cardboard with wood Make the inside circular rim of the clock slanted so that the strobe LEDs were more directed towards the extra hand. The sketch shows the sides are slanted instead of at an angle.
For this prototype, we incorporated the lighting, the clock, the strobing and a wood body. We also incorporated the strobe control using a microcontroller with BLE. Woodworking We wanted to construct a solid base for the clock and opted to make it out of wood. We designed three inner rings to be able to separate the large wooden base into makeable cuts. We also opted to make the rings with a slanted inner wall to be able to shine the strobe lights into the clock. After various troubled attempts, we were finally able to get a successful cut.
We then proceeded to sand these cuts and paste them together with wood glue. We use GSR to try to detect the arousal of a person, as changes in arousal are related to the perception of time.
In that first call we learned more from the reporter than he did from us. The media will often be the first on the scene, thus have information about the crisis before the organization does Berge, The team's strategy guidance from Burke was first, "How do we protect the people?

They told consumers not to resume using the product until the extent of the tampering could be determined. After finding 2 more contaminated bottles Tylenol realized the vulnerability of the product and ordered a national withdraw of every capsule Broom, The end result was the public viewing Tylenol as the unfortunate victim of a malicious crime Broom, The company used the number to respond to inquires from customers concerning safety of Tylenol.
They also establish a toll-free line for news organizations to call and receive pre-taped daily messages with updated statements about the crisis Berge, Several major press conferences were held at corporate headquarters.
Within hours an internal video staff set up a live television feed via satellite to the New York metro area. This allowed all press conferences to go national. Jim Burke got more positive media exposure by going on 60 Minutes and the Donahue show and giving the public his command messages Fink, Tylenol became the first product in the industry to use the new tamper resistant packaging just 6 months after the crisis occurred Berge, The initial media reports focused on the deaths of American citizens from a trusted consumer product.
In the beginning the product tampering was not known, thus the media made a very negative association with the brand name. All 3 networks lead with the Tylenol story on the first day of the crisis. CBS put a human face on the story which contained the following: Little did they know, they would wake up at 7: Throughout the crisis overseparate news stories ran in U.
Two news clipping services found overnews clippings on the Tylenol story. One of the services claimed that this story had been given the widest US news coverage since the assassination of President John F.
Media reporting would continue to focus on Tylenol killing people until more information about what caused the deaths was made available. In most crises media will focus on the sensational aspects of the crisis, and then follow with the cause as they learn more about what happened.
