  • Patent number: 5781882
    Abstract: An apparatus and method for processing a voice message to provide low bit rate speech transmission processes the voice message to generate speech parameters which are arranged into a two dimensional parameter matrix (502) including a sequence of parameter frames. The two dimensional parameter matrix (502) is transformed using a predetermined two dimensional matrix transformation function (414) to obtain a two dimensional transform matrix (506). Distance values representing distances between templates of a set of predetermined templates and the two dimensional transform matrix (506) are then derived. The distance values derived are identified by indexes identifying the templates of the set of predetermined templates. The distance values derived are compared, and an index corresponding to a template of the set of predetermined templates having a shortest distance is selected and then transmitted.

  • Patent number: 5742590
    Abstract: A stochastic method and apparatus schedules airtime in a radio communication system having a plurality of transmission protocols. At a queue measurement time airtimes are measured (402) that are required for transmitting messages stored in queues (222) corresponding to the plurality of transmission protocols. A corresponding plurality of estimated arrival rates are determined (404) equal to estimated rates of increase of the plurality of airtimes due to arriving traffic. An objective function is structured (408) equal to a sum of penalties corresponding to the plurality of transmission protocols, the penalties dependent upon the plurality of airtimes and the plurality of estimated arrival rates, and further dependent upon an optimal airtime allocation decision. The optimal airtime allocation decision is derived (410) by minimizing the objective function, and then airtime is allocated (412) among the plurality of transmission protocols in accordance with the optimal airtime allocation decision.

  • Patent number: 5737691
    Abstract: In order to allocate frequency channels to transmitter units, the transmitter units are grouped in zones, each zone having one or more transmitter units (10, 20, 30) therein. A system controller (40) calculates a zone priority value which is a function of the zone's message traffic level and message latency. The zone priority value determines the order in which a zone is assigned a frequency channel. A channel priority value is calculated for each channel or sub-channel that can be accessed by the transmitter units (10, 20, 10) in the zone based on a probability of success and a mean quality margin value wherein the priority value of a channel determines the order in which an available channel is considered for assignment to a zone. A proposed channel is assigned to a given zone only if the proposed channel passes a channel quality check. The channel quality check may be based on co-channel and adjacent channel interference values.

  • Patent number: 5716760
    Abstract: A novel process for plating a substrate without solder mask wherein the substrate is coated with a polymer catalyst to assist adhesion of conductive metal to the substrate. Next, a first plating mask photopolymer, or plating resist, is coated over the polymer catalyst, a circuit pattern is imaged onto the first plating mask and the first plating mask is developed to reveal windows, or circuit traces, in the first plating mask corresponding to the circuit pattern to be embodied on the substrate. Thereafter, a first conductive material such as copper is plated into the windows, and, thereafter, a second conductive material such as nickel may be plated into the windows on top of the first conductive material. Then, the first plating mask is removed from the substrate, leaving behind the conductive material in the form of the desired circuit pattern.

  • Patent number: 5697148
    Abstract: A method for dispensing underfill material between a flip chip bonded to substrate. The method requires an underfill injection port to be drilled through the substrate prior to reflow such that underfill material can be dispensed between the flip chip and substrate through the port. After reflow is completed, a pressurized pump delivers a predetermined amount of underfill under hydraulic pressure through the underfill injection port between the flip chip and substrate. Once injected, the underfill migrates between the flip chip and substrate via capillary action pushing out any air around the joints.
