The marker is compared to a predetermined value to determine that the protocol compatible marker signal is indicative of a spare wheel.Type: ApplicationFiled: November 14, 2006Publication date: May 15, 2008Applicant: NISSAN TECHNICAL CENTER NORTH AMERICA, INC.Inventor: Steven Paul Bothe

Publication number: 20080111673Abstract: A system, method and apparatus for modulated control of a vehicle lighting systems is useful for brake lights and/or running lights in a motor vehicle. Various vehicle operating parameters are monitored to determine an appropriate modulation control mode for the vehicle. In some examples, the engine speed (e.g., in revolutions-per-minute or rpm) or vehicle speed (e.g., in miles-per-hour or mph, kilometer-per-hour or kmh, etc.) is used as a parameter for modulated control of the lighting system. The modulated control scheme is used to control any number of features of the lighting system including illumination color, illumination intensity, selection of sequence illumination pattern, and adjustment of sequence rate. The modulated control scheme may be applied to off-road buggy whip-lights or other aesthetic vehicle lights and safety enhancements. The modulated control scheme may be applicable for off-road and on-road vehicle applications where localized government ordinances permit.Type: ApplicationFiled: November 15, 2006Publication date: May 15, 2008Inventor: Douglas Roberts

Publication number: 20080111674Abstract: A parcel includes a sensor to detect whether the parcel has experienced a change in condition. The parcel also has a mechanism, such as a changeable barcode, to indicate the change in condition. While the parcel is in transit through a parcel delivery system, a reader that is part of the system reads an indication from the parcel that the parcel has experienced the change in condition. The system may inform the sender and/or the recipient of the fact that the change in condition has been detected and may divert the parcel from delivery to the recipient. In this way, a parcel may self-monitor for potential damage, and the parcel delivery system may react to an event, in which a parcel suffers damage, before the parcel is delivered to the intended recipient.Type: ApplicationFiled: November 15, 2006Publication date: May 15, 2008Applicant: Pitney Bowes IncorporatedInventor: Douglas B.

Publication number: 20080111675Abstract: Some embodiments include observable properties triggered upon interrogation of RFIDs. The RFIDs can be passive RFIDs, and the observable properties can be visible changes that require little power to generate, and little or no power to maintain. The visible information can include information about items tracked with the RFIDs, such as shipping information. Some embodiments include passive RFIDs utilizing a single antenna to power an integrated-circuit chip and a visual identifier. Some embodiments include methods of locating interrogated RFIDs. Some embodiments include methods of tracking items.Type: ApplicationFiled: November 10, 2006Publication date: May 15, 2008Inventor: John R. Tuttle

Publication number: 20080111676Abstract: Apparatus and method for working with existing alarm monitoring systems to provide a second notification of an event at a remote location that is being monitored by the system that is directed to a law enforcement agency in the jurisdiction in which the remote location is located. As a result of this second, direct notification, the response time of the law enforcement agency is significantly reduced, increasing the likelihood that remedial action can be taken before injury or loss of life or damage to property.Type: ApplicationFiled: November 15, 2006Publication date: May 15, 2008Inventor: Glenn Cris Dobbs

Publication number: 20080111677Abstract: An alarm system for certain hearing impaired individuals having implanted hearing assistive devices contains a device for detecting an alarm condition, and a transmitter which is tuned to a resonant frequency of an implanted passive energy portion of a cochlear implant or similar device. Upon detection of an alarm condition, the transmitter transmits an alarm signal at the resonant frequency, causing the implanted device to resonate even in the absence of the externally worn hearing assistive portion. Resonance is perceived by the hearing impaired individual as a buzzing or other abnormal noise, alerting the individual to the alarm condition.Type: ApplicationFiled: November 9, 2006Publication date: May 15, 2008Inventors: Daniel Paul Kolz, Garry Joseph Sullivan

Publication number: 20080111678Abstract: The present invention is an article management system using a central management device with an interrogator and an alarm portion. Because the central management device and a central response device worn by a user of the system are provided separately, loss of the central management device can be prevented. The central response device is worn by a user. The central response device communicates with the central management device wirelessly and includes a detector that detects when the communication distance reaches or exceeds a given value and an alarm portion that notifies the user of this. The central management device communicates wirelessly with one or more articles in which a response device is installed.Type: ApplicationFiled: November 13, 2007Publication date: May 15, 2008Applicant: Semiconductor Energy Laboratory Co., Ltd.Inventors: Takafumi Mizoguchi, Hidetomo Kobayashi
