Abstract: The invention relates to a method of operating a communication network, the network comprising a plurality of stations which are able to transmit data to and receive data from one another so that a message comprising a plurality of data packets is sent from an originating station to a destination station via at least one opportunistically selected intermediate station. The method makes use of probe signals transmitted from each station on a selected probing channel to which other stations respond to indicate their availability as destination or intermediate stations. A Request to Send message is sent, with a Clear to Send message returned by an available station. The station with data to send opportunistically selects an available station and the selected station uses a Packet Acknowledge message to confirm successful reception of the transmitted data packet. An End-to-End Acknowledge message is sent by the originating station, directly or indirectly, to confirm receipt of said data packets.

Abstract: The present invention is a moisture-insensitive system adapted to couple radio frequency energy at a low impedance from a matched two conductor transmission line, through a vehicle windshield and to an antenna in a manner which minimizes stray radio frequency radiation within the passenger compartment of the vehicle. The system includes two pair of conducting plates, one pair mounted on each side of the windshield, each pair opposite the other pair. A coaxial feed line is coupled to the inside pair of plates and a matching circuit is connected across the outside pair of plates. A full-size, unloaded antenna element is connected to the output of the matching circuit. A decoupling device, such as a decoupling sleeve or a RF choke, can be used to minimize RF current flow on the shield conductor of the coaxial feed line. The coaxial cable is coupled directly through the windshield, without an intervening matching network, so that RF energy at a low impedance is coupled to the outside pair of plates. This low impedance minimizes parasitic coupling of the feed system to moisture on the windshield, windshield wipers and other foreign bodies. The elements of the invention cooperate to minimize the level of stray radiation within the passenger compartment of the vehicle and provide, in the illustrated embodiment, a 2.0:1 VSWR bandwidth that extends from 830 to 880 megahertz.

Abstract: Self relieving seals of this invention comprise an elastomeric seal body having a first sealing surface and a second sealing surface for contact with respective drill bit sealing surfaces. The seal includes a pair of external surfaces that each extend along the seal body between the first and second sealing surfaces. The seal includes one or more relief ports that are disposed through the seal body and that have openings through each of the seal body external surfaces. The relief port can be specially configured, e.g., have different diameter sections of constant or variable dimensions, to provide a degree of control over pressure equalization through the seal body when the seal is loaded within the drill bit. The seal may include an element, e.g., solid, tubular, or porous, disposed within the relief port to provide a further desired degree of control over pressure equalization through the seal when the seal is loaded within the drill bit. Surface features, on the seal or the drill bit, can be provided to offset the relief port opening from the rock bit so that it is not blocked off. The seal can include a valve mechanism to provide a further degree of control over fluid passage through the relief port.

Abstract: The invention relates to a method of operating a communication network, the network comprising a plurality of stations which are able to transmit data to and receive data from one another. The method comprises defining a first probing channel for the transmission of probe signals to other stations. Other stations which receive the first probe signals from a probing station indicate to the probing station their availability as destination or intermediate stations. A neighbor table comprising details of these other available stations is maintained at each station. Also, second probe signals are sent and received from stations in the neighbor table and a gradient table comprising data related to the cost of communicating with each neighbor station is maintained at each station, thereby to allow each station to select a predetermined number of intermediate stations for onward transmission of data from an originating station to a destination station at minimum cost.

Abstract: A key operated switch is provided for disabling an automobile air bag passive restraint system. The two or four position switch includes a housing, a rotor, a plurality of rotationally actuated electrical switch elements, a key ejecting mechanism, and a positive positioning detent. The switch assembly is arranged such that a transverse surface of the rotor defining a key slot is accessible through the housing. The key slot allows an operating key to be manually inserted into the rotor. In or order to insert the key, however, the therein, a certain minimum amount of force must be applied to the key sufficient to overcome the key ejecting mechanism. In the absence of such minimum insertion force, the key ejecting mechanism will act expel the key from the rotor. Once inserted into the rotor, the key may be manually rotated which causes corresponding rotation of the rotor. The rotation of the rotor in turn, actuates select electrical switch elements attached to the rotor, according to the angular position of the rotor. The electrical switch elements define a plurality of distinct switch states, each corresponding to a particular angular position of the rotor. Finally, the positive positioning detent forces the rotor to an angular position corresponding one of the distinct switch states defined by the electrical switch elements during those periods when no external torque is being applied to the rotor.

Abstract translation: 提供用于禁用汽车气囊被动约束系统的钥匙操作开关。 两个或四个位置开关包括壳体，转子，多个旋转致动的电气开关元件，钥匙弹出机构和正定位棘爪。 开关组件布置成使得限定键槽的转子的横向表面可通过壳体接近。 钥匙槽允许手动将操作键插入转子。 然而，为了插入钥匙，在其中，必须对钥匙施加一定的最小量的力以足以克服钥匙弹出机构。 在没有这样的最小插入力的情况下，钥匙弹出机构将起作用地从转子排出钥匙。 一旦插入转子中，钥匙可以手动旋转，这导致转子的相应旋转。 根据转子的角位置，转子的旋转依次驱动附接到转子的选择电开关元件。 电气开关元件限定多个不同的开关状态，每个状态对应于转子的特定角度位置。 最后，当没有外部转矩被施加到转子的那些期间，正定位定位力将转子施加到对应于由电开关元件限定的不同开关状态之一的角位置。
