Abstract: A system and method for interrupting a transmitting communication unit in a communication system. When a call is first initiated, the call is assigned to a communication channel and broadcast from a base site using the assigned communication channel. If it is determined that a transmitting communication unit should be interrupted, a zone controller signals a base site to generate an interrupt message. The base site generates an interrupt message containing an identification code for the transmitting communication unit and broadcasts the interrupt message on an outbound link of the communication channel. The transmitting communication unit, while transmitting on an inbound link of the communication channel, continuously monitors the outbound link. If the transmitting communication unit receives, on the outbound link, an interrupt message containing an identification code matching its own identification code, the transmitting communication unit stops transmitting.

Abstract: A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer.

Abstract: A receiving device in the trunked radio communications system receives an outbound signaling word comprising at least an opcode field and a band plan field, wherein the opcode field indicates that the outbound signaling message is a system status message and the band plan field indicates the band plan in use on the site. In another embodiment, the receiving device receives an outbound signaling word comprising at least an opcode field, a site identification field and a four bit band plan field, wherein the opcode field indicates that the outbound signaling message is an adjacent control channel message, the site identification field identifies a second site, and the four bit band plan field indicates the band plan in use on the second site.

Abstract: A multimeter for testing a plurality of electrical parameters comprises a case having a plurality of test lead jacks. Each of the test lead jacks includes a unitary conductive socket. Preferably, the sockets are made of metal such as brass. A circuit board located in the case has jack conductors in electrical communication with each of the sockets. A jack detection arrangement is adapted to automatically determine whether a plug is inserted into a respective one of the sockets based on a change in electrical characteristics. For example, the jack detection arrangement may include a photonic emitter and a photonic detector situated such that a beam path therebetween is interrupted by insertion of a plug. The case may further have a rotary selector knob for selecting a multimeter function.

Abstract: A computer program analyzes a CAD file provided by a customer of a custom part to be injection molded. Feedback from the analysis is provided to the customer through a rendering of the part. Rather than merely communicating using color as applied to the rendering file and separate text, the invention applies one or more symbols as “decals” to the rendering of the part provided to the customer. In one preferred embodiment, the symbols are chevrons or arrows which indicate the direction of additional draft needed on particular faces for the part to be sufficiently manufacturable. The symbols are sized appropriately for the size of the face to which they are applied, and are oriented to match the orientation of the face. The symbols may also indicate other information, such as the magnitude of draft needed, magnitude of thickness required, the surface finish to be applied at that location, or time or location based properties of the injection molding process.

The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities, surface finish and material, which an independent of the shape of the part.

Abstract: A system and method for effectively and reliably terminating a voice call in any burst within a multi-burst superframe. A transmitting unit generates a termination burst upon detecting a dekey event. The termination burst includes a data synchronization pattern, a slot type field indicating an end of a call, and an information field surrounding the data synchronization pattern and the slot type field. The information field is encoded from a predetermined voice encoder frame unique to the termination burst. Once all buffered voice information is transmitted, the termination burst is transmitted prior to the end of the multi-burst superframe. A base station or other receiving unit monitors the incoming signal. Upon detecting the data synchronization pattern, the receiving unit decodes the slot type field and the information field.

Abstract: A receiving device in a trunked radio communications system determines a transmit frequency, wherein the transmit frequency is calculated by subtracting a voice channel number from 759, multiplying by a channel spacing and adding a base frequency to yield the transmit frequency. The receiving device determines a receive frequency by a base frequency+[(759?a voice channel number)*25,000 Hz], where the base frequency is at least one of 851.0125 MHz, 851.0250 MHz, and 851.000 MHz. In any case, the voice channel number is communicated in an outbound signaling message defined by Motorola's 3600-baud radio trunking protocol.
