Abstract: A novel handheld compound archery bow (100) includes a riser (102) with a keyhole, an arrow rest assembly (150) extending through the keyhole, a bowstring (130), and a grip (106). A sabot (300) including top and bottom halves (301 & 302) each having three slots (310, 311 & 312) for holding two darts (200), such that a total of twelve darts may be loaded into the sabot. The top and bottom halves (301 & 302) once loaded with darts (200) are held together by rubber O-rings (380 & 381). The sabot (300) has a rectangular cross section and inserts into a corresponding rectangular opening in the muzzle end (152) of the arrow rest assembly (150). When shot from the novel handheld compound archery bow (100), the top and bottom halves (301 & 302) of the sabot (300) separate allowing the twelve darts (200) to continue unimpeded in flight toward a target. The twelve darts (200) disperse in an expanding pattern as they travel toward the target.

Abstract: The invention concerns a method of scheduling the time of transmission of one or more GPRS paging blocks in a cell of a cellular communications system, the paging blocks initiating communication to a mobile terminal in a cellular communications system, comprising calculating the transmission time of the paging block, or the transmission times of the paging blocks, in dependence on: (i) the number N determining which control channel carries the paging blocks of a given terminal; (ii) the number M of GPRS paging blocks on the control channel; (iii) the number KC of control channels in the cell of the cellular communications system; and (iv) the International Mobile Subscriber Identity (IMSI) number of the mobile terminal. The scheduling of the time of transmission of the one or more GPRS paging blocks in the cell of the cellular communications system may even out the distribution over time of the transmissions.

Abstract: A method and apparatus for controlling incoming power to a receiver in a dual mode communication device. According to the method and apparatus, the received signal is simultaneously processed by two separate filters, one filter to process the incoming desired communication signal and the other filter to process the noise for power estimation. With the communication device operating in a first mode initial filtering is attuned to the corresponding bandwidth. When the noise level reaches a predetermined level, the first bandwidth is adjusted to get a better estimate of the noise present. In Response to high noise levels, the incoming gain to the receiver is adjusted accordingly.

Abstract: A compound archery bow has a top cam which is larger than a bottom cam so that the nock point travel between an at-rest position and a fully-drawn position follows substantially a straight line. The nock point on the bowstring positions an arrow substantially perpendicular to the bowstring in the at-rest position. Since the nock point follows a straight line collinear with the arrow center line and perpendicular to the bowstring in the at-rest position, the arrow is released without nonlinear torque or movement of the nock end as it is pushed forward by the bowstring.

Abstract: A cellular radiotelephone or MS (100) includes an international mobile station identification including a mobile country code MCC, a mobile network code MNC, an area code MIN2 and a local number MIN1, all of which are stored in the EEPROM memory (124) of the MS. In the IMSI signaling system, a unique MIN1 coded number in the IMSIQ field of access and order messages is used to identify an IMSI access message from an IMSI MS or an IMSI order message from an IMSI base station or BS. In receiving order messages, an IMSI MS first looks for its MIN1, and if not found, then looks for unique MIN1 coded number in the IMSIQ field. If the unique MIN1 coded number is detected, the IMSI MS then looks for MIN1 in the last word of the message.

Abstract: A portable radio telephone is adapted to provide handsfree operation and adapted to be held against a user's ear to provide private operation. A housing of the portable radio telephone has an ear placement region on a front surface thereof. A speaker is disposed in the housing behind the ear placement region. The ear placement region is adapted to be held against a user's ear to provide private operation creating a first air volume between the user's ear and the ear placement region. In a preferred embodiment, an air path between the first air volume to a second air volume at the back surface of the housing includes at least a first port positioned within the ear placement region, an air cavity within the housing, and at least a second port positioned at a back surface of the housing.

Abstract: A radiotelephone (100) is coupled to accessory (200) by way of a novel interface provided by connector (190). Accessory (200) is a headset including a microphone (220) and a speaker (230) that may be plugged into a jack in radiotelephone (100) and worn by the user. Accessory (300) provides an RS-233 serial interface for communicating information between radiotelephone (100) and a personal computer (400). Controller (130) of radiotelephone (100) detects the presence of a 10K ohm resistor (202) to determine that accessory (200) is coupled to connector (190), and the presence of a 22K ohm resistor (202) to determine that accessory (300) is coupled to connector (190). When accessories (200) and (300) are detected, a liner regulator (116) is swathed on by controller to provide a 2.7V voltage source for powering accessories (200) and (300).

Abstract: A communications unit includes a processor (11), a data bus (12), an address bus (13), memory means (14,15,16), a data interface (36) between the data bus and a host computer (35), and a monitoring interface (30) with the host computer. The monitoring interface (30) includes monitoring address generating means fed from the host computer and including a bank register (31) loadable by the host computer as its high-order portion and a direct path (32) from the host computer as its low order portion. The monitoring interface also includes address coupling means (18) for passing the contents of the monitoring address generating means to the address bus (13) to address the memory means (14,15,16) of the communications unit directly. The host computer can also write to the unit via the monitoring interface.

Abstract: A housing unit (302) includes a latching mechanism (106) having a cylindrical head (202), a cylindrical rod (204), a cam (206), and a catch (208). The latching mechanism (106) is rotatably mounted in the housing unit (302). The catch (208) and a cam surface (216) of the cam (206) are rotatably exposable through an opening (164) on the housing unit (302) and the cylindrical head (202) is exposed through a circular opening (314) on the housing unit (302). When a battery door cover (102) meets with the housing unit (302) for attachment, a catch (118) of the battery door cover (102) rides the cam surface (216) to rotate the latching mechanism (106) until the catch (208) locks with the catch (118).

Abstract: An antenna (116) includes an antenna cap (1300), a helical coil (1302), and a bushing (1304). The antenna cap (1300) is sized to fit the helical coil (1302) and forms a bushing threading. The bushing (1304) forms a cylindrical portion (1320) and a cylindrical portion (1322). The cylindrical portion (1320) is sized to receive the helical coil (1302). The cylindrical portion (1322) defines a cap threading and is configured to threadedly receive the antenna cap (1300).

Abstract: A portable radiotelephone (100) has a signal quality indicator (110) disposed in a location on an outer surface of a housing thereof so that the indicator is within a peripheral view of the user when an earpiece (210) of the radiotelephone is held to a user's ear. In the peripheral vision of the user, the signal quality indicator (110) indicates a quality of the signal received by receiver (130) of the portable radiotelephone handset.

Abstract: A wireless communication device (10) is provided for maintaining acceptable acoustic coupling, increasing display and data input device capability and increasing antenna performance to encourage further miniaturization and weight reduction thereof. Two moveable housing portions (12) and (14) are moveable between a closed (18) and an open (20) housing position and matively engage to provide an expandable housing while aligning earpiece (26) and microphone (28) transducers on a center axis (30) of the device (10).
