Abstract: An intake manifold includes a plenum volume 14 mounted for movement within a housing 20 in response to a drive system 22 to define an effective runner length. A multiple of deformable runner passages 18 include a flexible section 26 such that as the plenum 14 extends and retracts within the housing 20, the flexible section 26 accommodates the difference in length while the housing 20 provides structural support therefor. An intake conduit 12 likewise includes a flexible section 26 to accommodate movement of the plenum 14. In operation at low engine speeds, the plenum 14 is driven to extend the deformable runner passages 18 to increase the length between the plenum 14 and the engine cylinders 16. As the engine speed increases, the plenum 14 is driven to shorten the deformable runner 18 for maximum speed operation.

Abstract: In a wireless communications system, transceivers transmit short bursts to a base station, which determines timing corrections from the time of receipt of the burst and transmits the timing corrections to the respective transceivers. In one aspect, the base station indicates to the transceivers a plurality of time slots, each transceiver selects one of the time slots at random, formats a burst including an Indicator of the selected time slot and transmits the burst in that slot. In another aspect, the base station transmits to each transceiver a timing uncertainty value, which determines how the timing correction will be modified by the tranceiver as the interval since last receiving a timing correction increases. Data bursts are transmitted in a format comprising a first unique word, a content field and a second unique word, in that order. The bursts are transmitted in a TDMA channel format which can accommodate both short and long bursts in a block format of constant periodicity.

Abstract: A radio frequency paging service has one or more TDMA return channels (R) in which terminals (14) acknowledge receipt of messages having an acknowledge flag set. In one alternative, slots are allocated in the return channel (R) by a slot allocation field in the respective messages. In another alternative, each terminal (14) monitors the messages addressed to other terminals (14) to determine which of them require a response, and determines, from the order of a message addressed to itself among the messages requiring a response, which slot to use for acknowledgement. The TDMA return channels (R) include unreserved slots which terminals (14) access on a contention basis. The frequencies of transmissions in the slots are randomized within a predefined limit to reduce the probability of interference between different terminals (14) in the same unreserved slot. The predefined limit is based on the maximum differential Doppler shift between terminals (14).

Abstract: An HQ tube arrangement suitable for packaging within a vehicle may be designed by creating a mathematical model representing a tube arrangement having a first passageway and a second passageway fluidly connected to the first passageway at first and second junctions. The second passageway is divided by the junctions into first, second, and third passages. Lengths may be associated with each of the first passageway and the first, second, and third passages to produce a particular length combination. A filter parameter, which may be passed upon an average transmission loss for a particular frequency over a standard deviation, is calculated for the particular length combination. Other lengths may be associated with the tube arrangement to calculate other filter parameters for the other length combinations.

Abstract: In a messaging system, message traffic is transmitted on one or more traffic channels T1, T2 and the allocation of groups S1, S2 of receivers to the traffic channels T1, T2 is controlled by information transmitted on a bulletin board channel BB. A predetermined number of frames before a change in the traffic channel allocation, a countdown value is transmitted in the relevant traffic channel T1 and the countdown value is decremented in each subsequent frame. Before the countdown value reaches zero, the groups of receivers S1, S2 retune to the bulletin board channel, receive their new channel allocations and retune to the traffic channel indicated for their group.

Abstract: An improved networked computer communications system handles arbitrary streams of data, and transports at varying speeds those streams where intermediate updates can be dropped if they are obsoleted by later arriving data updates, optimizing the utilization of network and node resources. Complex buffering by system server software allows distributed, parallel, or redundant processing, transmission, and storage for performance, reliability, and robustness. Various parameters of the system can be monitored, and the system can be reconfigured automatically based on the observations. Varied techniques reduce the perceived end-to-end latency and take advantage of software and hardware capabilities that assets connected to the system may possess. One conferencing system allows conference participants to share all or a portion of the display seen on their computer screens. The conferees may be at sites removed from each other, or may view a recorded presentation or archived conference at different times.

Abstract: An air introduction system (10) provides an active noise control system which includes a speaker assembly (28) in which the speaker support ring (36) is mounted to a speaker housing (32) without fasteners. In one speaker assembly, the speaker housing includes a plurality of extensions (40) which extend radially from an outer periphery of the speaker housing (32). The speaker support ring includes an edge (42) which at least partially surrounds the extensions (40). In another speaker assembly, the speaker support ring (50) includes a plurality of apertures (52) through a flange (54) which closely fits a speaker housing (32). The housing edge (54) and the speaker protection cone edge (56) are heated to a melting point of the material and the speaker support ring (50) is sandwiched therebetween. Heated material from the housing edge and the speaker protection cone edge pass through the apertures (52) to provide an effective bond therebetween.

Abstract: A movable microelectromechanical mirror structure for a microelectromechanical structure (MEMS) has an actuator (electrodes) for the moving mirror. The electrodes are situated at a predetermined angle to the horizontal thus improving the relationship between force applied on the mirror and the gap between the mirror and the electrodes. The angular electrode placement is achieved by the provision of a deformable electrode support member mounted on the substrate, with at least one of the electrodes mounted on the electrode support member, and a deforming element mounted against the deformable electrode support member such as to permanently maintain the deformable electrode support member in a deformed state.

Abstract: An engine noise control system (100) controls engine noise in multiple engine operating modes by controlling a size of an air inlet (104) with a movable valve. An actuator (114) moves the valve (112) between an open position and a closed position depending on the engine operating mode, to control the amount of air travelling into an air cleaner. The actuator (114) is coupled to an engine cylinder de-activation unit (200) to link the valve operation to the engine operating mode. When the engine is operating in a low-power mode, which requires less air, the actuator (114) moves a cable drive (204), which rotates an actuation lever (208) that turns the valve (112) into a closed position. When the engine is operating in a high-power mode, the actuator (114) moves the cable drive (204) to move the valve (112) to an open position.

Abstract: An active noise control system includes a speaker located within an enclosure within a vehicle body component. The speaker enclosure is typically located forward of a vehicle wheel well. An elongated transmission member communicates canceling noise from the speaker enclosure over the wheel well to an outlet adjacent the firewall. The elongated transmission member focuses and directs cancellation noise toward the firewall and bypasses the wheel well and any restriction created thereby.

Abstract: An active noise control system (100) and method compensates for changes in a microphone output to maintain accurate noise control. A calibration signal reflecting a desired microphone output is generated and stored in an active noise control module (106). During operation, the active noise control module (106) compares an actual microphone output signal with the calibration signal and compensates for any changes in the actual output signal before any noise compensation or cancellation function occurs.

Abstract: In a messaging system, message traffic is transmitted on one or more traffic channels T1, T2 and the allocation of groups S1, S2 of receivers to the traffic channels T1, T2 is controlled by information transmitted on a bulletin board channel BB. A predetermined number of frames before a change in the traffic channel allocation, a countdown value is transmitted in the relevant traffic channel T1 and the countdown value is decremented in each subsequent frame. Before the countdown value reaches zero, the groups of receivers S1, S2 retune to the bulletin board channel, receive their new channel allocations and retune to the traffic channel indicated for their group. The frame timings of the different traffic channels T1, T2 are staggered to reduce the peak power required to transmit message bursts in these channels.
