摘要： A lamp comprising a light source (18) and a reflector (26), wherein the reflector is of non-circular cross-section perpendicular to the longitudinal axis of the lamp and comprises several panels (20). Each panel has an undulating surface (22) that diffuses the light and so provides a relatively uniform level of illumination. The reflector panels may be concave and preferably form a hexagonal or square section reflector that is closed by a transparent cover (24). The lamp is provided for use as a recessed ceiling light and is secured by a circlip (44) and a sprung bracket mount (30). Also disclosed is a lamp with a non-circular section reflector formed from concave reflector panels.

摘要： A method is provided for vehicle to vehicle communication among vehicles having wireless communication links. Upon receiving notification of a sudden change in vehicle behavior, a vehicle broadcasts a priority message to surrounding vehicles within a transmission range. If an emergency event has occurred, a repeat cycle is defined for re-broadcasting the message, and a maximum number of initial repetitions for the message is specified. The message is transmitted repeatedly by a leader vehicle, with a pause between each transmission, until the maximum number of repetitions has been reached.

摘要： Systems and techniques for sensor-derived object flight performance tracking are described herein. A set of magnetometer readings may be obtained from a magnetometer included with an object. A local rotation axis of the object may be determined at a time using the set of magnetometer readings. The local rotation axis may describe rotation of the object around a local magnetic target. A global rotation axis may be calculated based on an initial orientation of the object. The global rotation axis may describe a fixed rotation axis of the object during flight in a global coordinate frame, wherein an angle between the global rotation axis and magnetic north remains constant during the flight. An orientation of the object may be determined for the time using the global rotation axis and the local rotation axis of the object at the time.

摘要： Embodiments herein relate to determining the location of a device using hybrid localization techniques. For example, a first technique such as trilateration may be used to determine an approximate location of the device. An error associated with the approximate location may also be implemented to increase the likelihood of locating the device upon applying a second localization technique, such as fingerprinting. Fingerprinting, when applied to the approximate location determined from trilateration, may determine the location of the device, or a more precise location than that determined from trilateration, such that reduced power consumption by the device may be achieved without sacrificing location accuracy.

摘要： Wireless location identification systems, methods, and devices include a wireless device configured to transmit at least one sonic signal operating on at least one acoustic frequency and to receive at least one echo signal indicative of the at least one sonic signal being reflected by objects in a current location, an audio module configured to measure the received at least one echo signal and process the at least one echo signal to extract attributes of the echo signal and generate at least one echo profile characteristic; and logic configured to compare the at least one profile characteristic with previously-stored sonic characteristics that are correlated with pre-identified locations. The current location is then identified as a pre-identified location correlated to the previously-stored sonic characteristics that match the at least one profile characteristic.

摘要： A system and method are provided for providing precise location sensing for wireless devices in an indoor environment using channel fading fingerprinting. An indoor environment within which wireless devices are used is surveyed to develop a channel fading database for the indoor environment. The surveying of the indoor environment determines a specific channel fading profile according to 30 subcarrier frequencies in a wireless signal for numerous locations within the indoor environment. A wireless device scans for available wireless access points and extracts a channel fading profile for a current location of the wireless device. The extracted channel fading profile for the current location of the wireless device is compared with the channel fading database. A best match comparison between the extracted channel fading profile and the channel fading database is used to determine an actual physical location of the wireless device in the indoor environment.
