  • Patent number: 5432844
    Abstract: A system of telephone answering devices includes a master telephone answering device (MTAD) and at least one (and often a plurality) of extension telephone answering devices (ETADs). If a telephone call is answered by someone, others nearby may be paged through the ETADs from any telephone. The ETADs can be temporarily disarmed so that they do not respond to tone codes that might otherwise activate them. When activated, the ETADs transmit back to the caller noticeably different ringback signals to indicate that the activated ETAD is responding to the caller's commands. For telephone utilities offering a distinctive ring service, the ETADs may respond to distinctive rings corresponding to the ETADs by usurping the function of and disabling the MTAD and by subsequently answering the telephone call.

  • Patent number: 5429762
    Abstract: A cooling agent which cools by an endothermic reaction resulting from the dissolving of crystals of inorganic salts water, the salts crystallizing at about room temperature by supplying heat. The cooling agent comprises a mixture of (i) a sodium phosphate salt, (ii) a sodium ammonium phosphate salt or an ammonium phosphate salt, and (iii) water. The cooling agent is produced in a manner which avoids the conglomeration of the crystals, which was a difficulty in the art. Moreover, the cooling agent of the present invention can be used repeatedly. When a nucleating agent, a highly water absorbent polymer or a thickener is added to the cooling agent, the precipitation of the crystals occurs in a still finer and stabler state. The cooling agent can be used in a cooling pillow having a desirable cooling property and a soft and agreeable touch, which offers comfort with safety and which is free from conglomeration of crystals, even after a long period of time.

  • Patent number: 5430890
    Abstract: Digital tuning of a locally generated frequency supplied to a frequency converting mixer, a mobile radio receiver is provided with great economy of components by utilizing the sampling rate oscillator for an analog-to-digital converter provided at the output of an analog intermediate frequency amplifier of the receiver as the source of the difference frequency for a phase locked loop (PLL) for control of the phase of a local oscillator for the mixer or mixers. All frequencies used to supply local oscillations to mixers, as well as the operating frequency of the phase locked loop are integer number multiples of the sampling rate pulse generator. Some division stages have fixed dividers and others have divisors selectable by a tuning processor and in some of the divisor connections it is useful to interpose a fixed or selectable-factor multiplier. A sampling rate of 42.75 MHz is recommended and an intermediate frequency amplifier frequency which is a rational number multiple of 57 kHZ, preferably 10.

  • Patent number: 5430283
    Abstract: In the data processing circuit of a decoder box, the position sensing circuit senses the position of the bar-code symbol imaged by a video camera in the imaging area of the video camera on the basis of the output of the frame memory. Then, the shift direction judging section of the data processing circuit determines the direction in which the bar-code symbol imaged by the video camera is shifted with respect to the imaging area of the video camera on the basis of the output of the position sensing section. The display control section of the data processing circuit displays the position of the bar-code symbol on a label position indicator provided on the decoder box on the basis of the judgment result of the shift direction judging section.

  • Patent number: 5430831
    Abstract: A method of optimally packing, either intermittently or continuously, a storage or transportation area or space with rectangular parallelepiped objects, e.g. parcels, comprises two main steps of complex calculations. A first main step implies the locating of one or more free subareas or free subspaces on the area or in the space available for packing by means of a matrix reduction procedure for a 2- or 3-dimensional matrix representing free and occupied parts of rectangular or rectangular parallelepiped form. In a second main step a score is established for each different combination of a free subarea or subspace and an object to be packed and a possible orientation of the object for fitting in the subarea or subspace. The score is established by assigning a score value to each combination by passing through a hierarchy of determinations, whereby a score is the more favorable if the score value is assigned at a higher level in the hierarchy.

  • Patent number: 5430513
    Abstract: A film cartridge in which a supply spool incorporated in a cartridge body is rotated to supply a film wound on the supply spool out of the cartridge body. A film supply unit rotates the supply spool to supply the film out of the film cartridge. A first control unit controls the film supply unit such that a supply operation of the film is started in response to a closing operation of the rear cover of a camera body. A film take-up unit takes up the film supplied by the film supply unit. A second control unit controls the film take-up unit to operate the film take-up unit upon completion of the supply operation of the film performed by the film supply unit. A third control unit interrupts a take-up operation of the film performed by the film take-up unit and reoperates the film supply unit when the take-up operation of the film is impossible during the take-up operation of the film performed by the film take-up unit.

  • Patent number: 5428989
    Abstract: Arrival of a pressure wave front is detected at a plurality of monitoring stations spaced along a protected section of a fluid-carrying pipeline. Arrival times obtained at the monitoring stations are qualified as to whether they correspond to a pressure transient event (critical event) which originated in the protected section. If so, the location, amplitude and time of occurrence of the critical event are determined. An uncertainty zone is derived at the extremes of the protected section having a length dependent on the precision of a time standard to which the monitoring stations are referenced and on the exactness of fluid velocity in the pipeline. An operator is so informed if the location of the critical event is determined to fall in the uncertainty zone. It is also possible to determine whether wave fronts correspond to an event occurring outside the protected section. Information from the resulting pass-through wave is used to update needed parameters useful for the critical event determinations.

  • Patent number: 5428827
    Abstract: A radio data system (RDS) receiver has a station selector circuit including a microprocessor, several Alternative Frequency (AF) memory cells, and at least one learning memory cell associated with each AF memory cell. In a preferred embodiment, a counter is associated with each learning memory cell. The AF memory cells store alternative frequencies decoded from a Radio Data System signal. As each station is tuned successfully, i.e. with adequate signal strength, its frequency is stored in one of the learning memory cells. When signal deterioration requires a skip to a new frequency, the "skip frequencies" stored in the learning memory cells are preferred to other frequencies. The counters keep track of how many times, since power-up, each frequency has been successfully tuned, and the frequency with the highest count is the "most preferred" alternative frequency.
