  • Patent number: 11946892
    Abstract: For moisture detection and prevention systems, the reduction or prevention of false positive and false negative alarms is of immense economic value. A method of discriminating the types of materials in contact with a capacitive detector can be easily implemented even for battery-powered devices and has already proven useful in testing in preventing false alarms, and discriminating various solutions.

  • Patent number: 11519633
    Abstract: The present disclosure is directed to implementation of an environmental control unit using rotomolded techniques to fabricate the structures of the unit instead of the standard conventional sheet metal, extruded, forged, and punched parts. Such implementations will provide a lighter weight and more durable mechanical configuration that will also simplify inspection, simplify assembly/disassembly, and reduce fabrication costs. Implementations incorporate rotationally-molded interlocking structures to contain and attach the critical items of the ECU's mechanical components including the compressor, and the indoor and outdoor coils, as well as the fan and blower motor assembly. In one implementation, the rotomolded structure is strengthened and insulated (thermally and acoustically) by filling the interior void of the rotationally molded structure with a closed-cell foam.

  • Patent number: 5764947
    Abstract: A jacketing system automatically interfaces dissimilar program units during program execution on a computer system. Means are provided for detecting a call for execution of a second program unit having a second call standard form a first program unit having a first call standard during execution of the first program unit on the computer system. A procedure descriptor is used in the code for the first program unit and it includes a signature that defines the call standard for each incoming call to the first program unit. A bound procedure descriptor is also used in the code for each outgoing call from the first program unit and it includes a signature that defines the call standard for the target program unit. Jacketing routines are driven by the descriptors in jacketing calls between the two program units.

  • Patent number: 5442336
    Abstract: A system and method for temporarily disabling a smoke detector alarm unit. The present invention includes a switch between the main assembly and the power assembly of the unit and a timer for monitoring a predetermined length of time. The switch is caused to break the circuit between the main assembly and the power assembly while the timer monitors the passage of time. Once the predetermined length of time has passed, the switch is caused to reengage the circuit between the main assembly and the power assembly.

  • Patent number: 5297291
    Abstract: An improved method for linking images at program activation is provided by use of a symbol vector in a sharable code image. The symbol vector is automatically constructed which the linker and operating system use to effect fast lookup of symbol values at program activation, thus providing flexibility similar to that of link-time binding. For each sharable image being constructed, the programmer provides a list of symbols which are to be made visible outside of the image. These symbols may be procedure names, data cells, absolute values, or any other valid use of a symbolic value. The order of this list must remain fixed from one image build to the next. From this list, the "symbol vector" is constructed (as by the linker) of the value of each of the identified symbols, and the symbol vector is associated with the sharable image. A symbol table is also associated with the sharable image, where each symbol has the value of its index in the symbol vector.

  • Patent number: 5223815
    Abstract: A portable anti-theft system and method for sounding an alarm which is a speech synthesizer when a first portable unit and a second portable unit become separated by a predetermined distance is disclosed herein. The system comprises transmitter means in the first portable unit for transmitting a signal, receiver means in said second portable unit for receiving the signal transmitted by the transmitter means, signal strength determination means in communication with the receiver means for comparing the strength of the received signal with a predetermined signal comprising speech synthesizing means for making an announcement when the signal strength determination means has determined that the strength of the received signal is less that the predetermined signal strength value.

  • Patent number: 5137279
    Abstract: The board game of the present invention is a political candidate campaign board game, wherein the object of the game is to obtain score points in the form of votes. There are two playing surfaces and two distinctive playing pieces are assigned to each player. One playing surface is a path portion with indicia containing political questions and the second surface is a geographic portion with indicia containing electoral votes required to win a particular geographic region. The board game may further include three sets of cards: "Ad Cards", "Consultant Cards" and "Theme Cards". The set of "Ad Cards" contain "Attack Cards" and "Rebuttal Cards" to be used in conjuction with answers players may give to the indicia containing political questions on the path portion.

  • Patent number: 4388685
    Abstract: A central processor for use in a data processing system that is adapted for addressing a substantially larger virtual memory than the address space defined by the memory address field in an instruction normally provides. Information identifying an extended address is placed in working registers of the central processor. Other working registers in the central processor receive information corresponding to the memory word addressed by the instruction word. If the memory word requires indexing, the central processor adds the contents of an index register to the address contained in the memory address field of the memory word. If the resultant address is extended, the arithmetic and logic unit's carry logic is not inhibited and the larger address space is provided to one of the working registers. Concurrently, control logic is set within the central processor which causes the central processor to interpret the information as an extended address.
