Abstract: The present invention is a user equipment (UE) which receives a communication signal over a physical reference channel using a reference channel receiver. An expected path loss is calculated using a path loss calculation device in response to the received communication signal. A signaling receiver receives an allocation of an uplink control channel including the amount of interference in the channel. Then, a power level calculation device, responsive to the path loss calculation device and the signaling receiver, determines an uplink power level based on the path loss and the interference level, whereby an uplink control channel transmission is initiated having the power level determined by the power level calculation device.

Abstract: The present invention is a base station which receives a communication signal over an uplink common control channel and measures interference on the uplink common control channel in response to the received signal. A channel quality measuring device included in the base station monitors the channel quality of the uplink common control channel and provides a quality margin for the communication signal. A spreading device, then, transmits the quality margin over a downlink control channel in response to the quality margin.

Abstract: A sequence of codes are provided for potential assignment to a user in a wireless hybrid time division multiple access (TDMA)/code division multiple access (CDMA) communication system. At least one timeslot is selected to support the communication. For each selected timeslot, at least one code is selected. If more than one code is selected, the selected codes are consecutive in the provided codes sequence. For at least one of the selected timeslots, an identifier of a first and last code of the selected consecutive codes is signaled. The user receives the signaled identifier and uses the selected consecutive codes, as identified, to support the communication.

Abstract: In a wireless digital communication system employing code-division multiple access (CDMA) technology, a method in which adaptive modulation and coding (AM&C) is utilized in order to achieve improved radio resource utilization and provide increased data rates for user services in which the base station measures up link interference on all time slots received from mobile terminals (UEs) and determines the need for uplink control channel; the base station transmitting to the UE the allocation of specific uplink control channels indicating uplink interference in the time slot and potentially the quality margin; the UE determining appropriate uplink power level based on a path loss determination made by the UE, uplink interference and the quality margin; the UE initiating an uplink common control transmission responsive to these determinations.

Abstract: Method of filling a silencer with a sound insulating material includes inserting a nozzle into a silencer and feeding sound insulating material, preferably continuous texturized glass, or basalt, or mineral fiber, through the nozzle into the silencer. The nozzle reciprocates linearly and retracts from the silencer while the fibers are being fed into the silencer. The silencer may be rotated while the sound insulating material is fed into the silencer. The nozzle is reciprocated into and out of the silencer and the silencer rotated clockwise or counter-clockwise to control the density and distribution of fill.

Abstract: In order to obtain speed and position information about a moving component of a musical instrument a fin extending in the direction of travel of the moving component is coupled thereto as, for example, by affixing the fin to the hammer shank of a piano. The fin carries indicia, such as a bar code, which can be read, for example, by an optical or magnetic sensor assembly. In one embodiment, a pair of side-by-side indicia bands are carried on the fin with the bands slightly offset in the direction of travel in order that direction, as well as speed and position information can be obtained. The gathered data may include information recorded, for example, for all the notes and the pedals of a piano in order that a performance may be reconstructed and played back employing a solenoid stack or the like.

Abstract: Improved devices for controlling vehicular traffic are disclosed. The present invention permits the installation of collapsible bollards or posts to create a barrier to vehicular traffic. The bollards disclosed use an internal latch bar and a hinged connection allowing them to be collapsed using an ordinary fire hydrant wrench, thereby permitting access by fire and emergency vehicles to the areas protected by the bollards. Moreover, in the preferred embodiment, a novel spring-loaded latch bar, entirely contained within the bollard and protected from the elements, permits the bollards of the present invention to be reset in a locked position without the use of a hydrant wrench or other tools. Other embodiments disclose how the bollard may be re-locked without the use of tools when the bollard is returned to an obstructing position.
