Abstract: A method for etching (200) photolithographically produced quartz crystal blanks for singulation. First, a quartz wafer is plated on both sides with metal and subsequently coated on both sides with photoresist (202). Second, the photoresist is patterned and developed and the metal layers etched to define the periphery of a quartz blank with a narrow quartz channel exposed between the blank to be singulated and the parent quartz wafer (204). Third, the quartz channel is preferentially etched partially into the wafer along parallel atomic planes to provide a mechanically weak junction between the quartz wafer and the blank to be singulated, while the periphery around the remainder of the quartz blank is etched completely through the parent quartz wafer (206). Fourth, the photoresist layers are stripped from the quartz wafer (208). Finally, the quartz blank is cleaved substantially along the bottom of the quartz channel to singulate the crystal blank from the wafer (210).

Abstract: The method and microprocessor of the present invention includes a step of calculating the angle changes, in the handwritten input (108). The method then selects potential segmentation points in the input whose angle change exceeds a predetermined threshold (110). The segmentation points are used to determine a sequence of straight line strokes that may be used by a recognizer for interpretation of the handwritten input (114).

Abstract: A selective call receiver (10) has a base unit (12), a moveable cover (18), and an antenna (34). Within the base unit (12), an adjustable impedance matching network (36) is provided between the antenna (34) and receiver circuitry (42). When the cover is closed, the network (36) provides a predetermined impedance which compliments the body effect of the user to provide maximum power transfer between the antenna (34) and the receiver circuitry (42). When the user opens the cover (18), a switch (32) is activated to cause a control circuit (62) to develop a control signal that is applied to the matching network (36) for causing the matching network (36) to adjust its impedance to compensate for the assumed loss of the body effect.

Abstract: A low power regenerative feedback device (301) and method automatically increases bias current during positive large-signal slewing, enabling output to change faster. The device includes a voltage transforming unit (302), adaptive regenerative feedback circuitry (304) and an output stage (309). When the device is not in a positive slew, bias currents are unchanged, providing a low standby current. Since regenerative feedback is internal and automatic to the device, current is increased only for the device driving an active column of an LCD panel. Thus, the present invention is power efficient. In addition, the AC response of the device is preserved because the device utilizes a regenerative feedback circuit (304) that does not add appreciable excess phase shift. The device achieves an output that switches readily from positive supply to negative supply.

Abstract: An opto-isolator (10) increases optical efficiency by using holographic elements (22, 24, 26) to direct a beam of light (34) through an optical waveguide (20). An opto-electronic transmitter (12) and receiver (16) are connected to the waveguide to be in alignment with the beam of light reflected by the holographic elements.

Abstract: In a cellular communication system (40) a handoff candidate list is generated for a source sector (51) by eliminating (12) from a list of potential handoff candidates (52-56) any sectors having an interference parameter exceeding a threshold value. The list is further reduced by determining (21) a handoff radius (60) and eliminating any candidate sectors (52-56) that fall outside the hadoff radius (60). Candidate sectors (52-56) that do not have overlapping coverage areas are also eliminated (23). In addition, candidate sectors (52-56) having a relative angle of sight to the source sector (51) that exceeds a maximum angle are also eliminated (24). Finally, the list is reduced (15) to a preset number of candidates dependent upon the interference parameter.

Abstract: A control station (8) is coupled to a plurality of tributary devices (16, 18, 20) by way of at least one high speed broadcast downstream data channel (9) and more than one shared lower speed upstream data channels (11, 13). The control station (8) broadcasts data to all the tributary devices (10, 16, 18) and selects a channel for a specific tributary device (16, 18, 20) to respond to a poll. After polling, the tributary device (10, 16, 18) changes the tributary device transmitter (42) to the frequency of the selected channel. The tributary device (16, 18, 20) either sends data to send to the control station (8) or sends a negative acknowledge to the control station (8). If a negative acknowledgment was transmitted, the control station (8) notifies the control station transmitter (10) that the channel is idle.

Abstract: A selective call system (100) has a plurality of base sites (120-124) for communicating with a plurality of selective call receivers (108) with acknowledge-back capability. A base site transmitter (210) transmits signals encoded with a stored location identifier (132), a base site receiver (241) receives acknowledge-back signals in response to the transmitted signals and a controller (206) determines when a selective call receiver (108) is authorized to receive location specific information (134). The base site transmitted (210) downloads the location specific information (134) to the selective call receiver (108) in response to verifying that the selective call receiver (108) is authorized. The selective call receiver (108) receives the signals having the location identifier (132) and the downloaded location specific information (134). A decoder/controller (306) compares the location identifier (132) received with the stored location identifier (108) of selective call receiver (108) to determine when the selective call receiver (108) has roamed to the new service area and stores the new location identifier (132). An acknowledge-back transmitter (334) transmits the new location identifier (132) to a home service area for enabling paging information to be routed from the home service area to the selective call receiver (108) at the new service area.

At least a first Master device and a plurality of Slave devices utilize the steps of: (1) transmitting, by the plurality of Slave devices upon receiving a contention poll from the first Master device, information to the Master device, wherein transmissions of the Slave devices provide a collision (1002); (2) selecting a subset of Slaves allowed to retrsnsmit following the collision, by the first Master device using a collision resolution poll in accordance with a predetermined depth first tree search technique (1004); and (3) retransmitting, by the subset of Slave devices, the information to the Master device, and, where another collision is obtained, recycling to step 2 and repeating steps 2 and 3 until all collisions are resolved (1004, 1006 and 1008).
