Abstract:
A sensor system for protecting a door (16) of a vehicle (10) from damage includes an electronic sensor (12) operable to detect when an object (14) external to the vehicle is within close proximity to the door (16) of the vehicle. The sensor system provides a signal indicative of the proximity of the external object (14). The sensor system also includes a blocking hinge mechanism (22) coupled with the signal. The hinge mechanism blocks (22) the opening of the door (16) beyond a distance wherein the vehicle door would strike the object (14).
Abstract:
A communication device (100) includes a transceiver (115) for receiving a call, a received calls memory (145) for storing call sources (300) and for storing an associated call count (315) for each call source (310), and a processor (120). The processor (120) is programmed to: identify a call source of a received call, generate a command signal to an alert circuit (130) identify a unique alert associated with the call count, and increment the call count. The communication device (100) further includes the alert circuit (130) for alerting using the unique alert identified by the processor (120).
Abstract:
A method of inter-area rekeying of encryption keys in secure mobile multicast communications, in which a Domain Group Controller Key Server (Domain GCKS) distributes Traffic Encryption Keys (TEK) to a plurality of local Group Controller Key Servers (local GCKS), and said local Group Controller Key Servers forward said Traffic Encryption Keys, encrypted using Key Encryption Keys (KEKi, KEKj) that are specific to the respective local Group Controller Key Server (local GCKSi, GCKSj), to group members, said local Group Controller Key Servers (GCKSi, GCKSj) constituting Extra Key Owner Lists (EKOLi, EKOLj) for group key management areas (areai, areaj) that distinguish group members (MMi, MMj) possessing Key Encryption Keys (KEKi, KEKj) and situated in the corresponding group key management area (areai, areaj) from group members (MMij) possessing Key Encryption Keys (KEKi) that were situated in the corresponding group key management area (areai) but are visiting another area (areaj).
Abstract:
A flexible active signal cable (100, 200) includes a flexible printed circuit substrate (105), two electrical connectors (110), at least two metal conductors (115), at least one flexible optical waveguide (120), an optical transmitter (125), and an optical receiver (130). In some embodiments, the flexible active signal cable is less than 0.5 meters long and is capable of being wrapped and unwrapped from a 5 millimeter diameter mandrel 10,000 times with a low probability of failure at a test temperature, while supporting data rates greater than 25 megabits per second.
Abstract:
A Q-Filter is a reconfigurable technique that performs a continuum of linear and nonlinear filtering operations. It is modeled by unique mathematical structure, utilizing a function called the Q-Measure, defined using a set of adjustable kernel parameters to enable efficient hardware and software implementations of a variety of useful, new and conventional, filtering operations. The Q-Measure is a novel is based on an extension of the well-known Sugeno Q-Measure.
Abstract:
A method for equalizing a speech signal generated within a pressurized air delivery system, the method including the steps of: generating an inhalation noise model (1152) based on inhalation noise; receiving an input signal (802) that includes a speech signal; and equalizing the speech signal (1156) based on the noise model.
Abstract:
In one embodiment of the present invention, an access point (111) receives a multicast packet intended for a particular multicast group. Upon receipt, the access point only rebroadcast the multicast packet over a wireless segment if it determines that there is at least one wireless subscriber unit (131) belonging to the particular multicast group and associated with the access point that did not originate the multicast packet. Optionally, if the multicast packet signals an automatic rebroadcast of the multicast packet over the wireless segment, the access point automatically rebroadcasts the multicast packet without determining whether there is at least one wireless subscriber unit belonging to the particular multicast group and associated with the access point that did not originate the multicast packet.
Abstract:
Un sistema mejorado y procedimiento para permitir a los participantes dentro de una conversacion de grupo en una red de comunicacion inalambrica (10) separarse por lo menos temporalmente de una conversacion de grupo (90) y mantener una conversacion de barra lateral; la conversacion de barra lateral (100) puede comprender varios tipos diferentes, incluyendo una conversacion publica o puede estar formada por una conversacion privada o envio de texto privado o intercambio de datos; un usuario de conversacion de grupo que desea mantener la conversacion de barra lateral utiliza su interfaz de usuario para enviar una alerta a otro u otros usuarios de conversacion de grupo con quienes le gustaria mantener la conversacion de barra lateral; ya sea el usuario que inicia o el usuario o usuarios receptores pueden recomendar el tipo de conversacion de barra lateral que se va a tener utilizando sus interfases de usuario (51); si la conversacion de barra lateral es una conversacion de voz, la conversacion del grupo original se puede seguir escuchando en el fondo, pero se puede reducir su volumen con relacion a la conversacion de barra lateral o se puede silenciar dentro y fuera cuando esta activa la conversacion de barra lateral.
