Abstract: The present invention encompasses a method of facilitating talkgroup communications across a multiple-system communication network (100). A typical multisystem network (100) includes a plurality of communication units (122), a plurality of communication location areas (117-119), and a plurality of system controllers (100, 116). Upon migration of a communication unit (122) from one communication system to another, the communication unit (122) sends a registration request to the system controller (116) at the new communication system (102). The system controller (116) determines whether the talkgroup of the migrating communication unit (122) is registered with the new communication system (102). If the talkgroup is not registered with the new system (102), a database (120) is updated with the new talkgroup information, thereby facilitating talkgroup communication involving members of the talkgroup.

Abstract: A battery pack (12) for powering a device (14) sensitive to input voltage contains a protection switch (28) and a control circuit (26). When the battery pack (12) is charged by a charger (10) and the voltage of the battery pack approaches the maximum safe level of the device (14), the control circuit (26) causes the protection switch (28) to electrically switch open to protect the device (14) from excessive voltage potentially output by the charger. Where the cells (16) are lithium ion cells or a type having a maximum safe voltage, a safety switch (49) is included to interrupt charge current (52) through the cells (16). The safety switch (49) is delayed by resistor/capacitor network (51, 53) so that it switches after the protection switch (28). The safety switch (49) includes a diode (58) to allow the device (14) to remain powered while the safety switch is blocking charge current. Further, diodes (40 and 42) are required to eliminate measurement error of the control circuit (26) if the battery pack (12) is charged through the device contacts (20 and 24).

Abstract: A circuit (100) includes an antenna switch having desired components (106) and stray components (104, 108) associated therewith. The circuit (100) also includes a filter combined with the antenna switch circuitry. The filter circuit uses the stray capacitance (104, 108) of the switch circuit to realize its intended function. Such an efficient use of the stray components of one circuit by another provides for a spatially efficient substrate.

Abstract: The masking level for a particular subband in a subband audio encoder is efficiently calculated by the present invention. The first step is calculating a signal level for each of the subbands based on an audio frame (102). Then, the masking level is calculated for the particular subband based on the signal levels, an offset function, and a weighting function (104).

Abstract: A first communication unit (101) transmits, to a central controller (105), a request for a group call. The central controller allocates a first inbound (I1), a second inbound (I2), and a outbound (O1) wireless communication resource for use in the group call. At the central controller, primary voice signals from the first communication unit, received via the first inbound wireless communication resource, are summed (109) with interrupt voice signals from a second communication unit (102), received via the second inbound wireless communication resource, to produce summed voice signals. The summed voice signals and a busy signal (108) are transmitted via the outbound wireless communication resource, thereby allowing the second communication unit to interrupt the group call. Additionally, the central controller can allocate a thrid inbound communication resource (I3) for use with priority interrupt voice signals which can also be summed with the primary and interrupt voice signals.

Abstract: Ferrite films are formed by reactively sputtering elemental iron in an oxygen-containing plasma to deposit a layer of iron oxide (14) on a ceramic substrate (12). A dopant layer (16) of a transition metal-oxide is reactively sputtered onto the iron oxide layer from a target of a transition metal, such as nickel or zinc, using an oxygen-containing plasma. The substrate, the layer of iron oxide and the dopant layer are all heated under conditions sufficient to diffuse the dopant layer into the layer of iron oxide, thereby forming a doped ferrite thin film (20). The resulting doped ferrite film can be FeFe2O4, NiFe2O4, (NiZn)Fe2O4, or ZnFe2O4.

Abstract: A method and apparatus for mitigating error in a received communications signal includes an error mitigator (35) of a communication unit (12) which receives and performs mitigation based on an error indication. In a first embodiment, the error indication is a phase or non-used data symbol indicating error in ADPCM data, and mitigation includes changing certain nibble values to different predetermined values. In a second embodiment, the error indication may include other parameters, e.g., a CRC frame error indicator, and an error estimator (34) determines a level of corruption in the ADPCM data. The error mitigator (35) applies a predetermined set of replacement values based on the indicated level of corruption, and the mitigated data is subsequently decoded in an ADPCM decoder (26).
