  • Publication number: 20020193028
    Abstract: A coating composition for fabrics includes wetted microspheres containing a phase change material dispersed throughout a polymer binder, a surfactant, a dispersant, an antifoam agent and a thickener. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. To prepare the coating composition, microspheres containing phase change material are wetted ahd dispersed in a dispersion in a water solution containing a surfactant, a dispersant, an antifoam agent and a polymer mixture. The coating is then applied to a fabric. In an alternative embodiment, an extensible fabric is coated with an extensible binder containing microencapsulated phase change material to form an extensible, coated fabric. The coated fabric is optionally flocked. The coated fabrics are manufactured using transfer techniques.

  • Patent number: 5805685
    Abstract: A system and method for analyzing audio signals sampled from a telephone line during moving sample windows in order to detect indicia of three way calling attempts. The system and method sample audio signals on the telephone line, sort the sampled signals into a profile of levels for the sampled audio signals, and monitor the profile of sampled audio signals for reset and reference conditions. Reset conditions are pulse patterns identified from sampled audio signals that are inconsistent with patterns generated by three way call events. Reference conditions are pulse patterns identified from sampled audio signals that are consistent with patterns generated by three way call events. A sampling window and its associated profile are reset when reset conditions are detected. The profile is tagged as a potential three way call event when reference conditions are detected in a sample profile and no reset conditions are detected over the selected sampling interval (sampling window).

  • Patent number: 5677048
    Abstract: A coating composition for skived foam substrates includes a polymer binder in which microspheres containing a phase change material are dispersed. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. The preferred substrate is a skived polyurethane foam of from 20 to 90 mils in thickness, having up to 6 ounces per square yard or more of encapsulated phase change material embedded in a polymer binder. Polyether and polyester urethanes are preferred. A preferred method of applying the binder with embedded encapsulated phase change materials using knife over roll technique to an exposed surface of the skived foam is disclosed in which the most preferred viscosity of the uncured polymer binder is from 7,000 to 9,000 centipoise.

  • Patent number: 5535261
    Abstract: A system for controlling and monitoring the recording of telephone calls in institutions such as jails and correctional facilities. Calls are recorded automatically in response to the occurrence of specific triggering events, as pre-defined under software control by a system administrator. Triggering events may include, for example, use of a specific line, attempts to use particular features (such as three-way calling), attempts to dial particular telephone numbers, or use by a particular person. Recorded calls are digitized and stored in standard MS-DOS files on either a local computer system or a remote computer across a network. Stored digitized recordings may be selected for playback under software control by a system administrator. The system of the present invention allows control of recordings from within a conventional telephone system. The integrated nature of the system provides cost savings and improved flexibility.

  • Patent number: 5532039
    Abstract: A thermal barrier for controlling heat transfer across through buildings, appliances and textile products is disclosed. The thermal barrier includes opposing, spaced apart sheets which define at least one chamber therebetween. A temperature stabilizing material is disposed in the chamber. The temperature stabilizing material is preferably a phase change material such as a paraffinic hydrocarbon, hydrated salt, plastic crystal or glycol. In one embodiment, an interconnecting structure is disposed between opposing sheets to create a plurality of cells of the chamber into which the temperature stabilizing material is uniformly disposed. A method of manufacturing the thermal barrier is also disclosed.

  • Patent number: 5485507
    Abstract: A commissary system for receiving and processing commissary orders using a premise-based telephone system of an institution such as a jail or correctional facility without accessing a PSTN. User-provided identifier information and item selection information is entered into the commissary system through selected telephones of the premise-based telephone system. User status and inventory information stored in a memory device coupled to a processor are compared with the user provided identifier and item selection information by the processor, according to selected authorization criteria. These criteria may include sufficiency of the user's account balance, item availability, and scope of the user's commissary privileges. The processor generates transaction records for user identified items that meet the authorization criteria, automatically adjusts inventory and user status information, and stores the records in a file where they may be downloaded for record keeping purposes.

  • Patent number: 4499531
    Abstract: A self-referencing self-oscillating power converter is disclosed. The power converter operates in the flyback switch mode to convert a high voltage DC power source to low voltage regulated power supply voltages applied to a load. Energy is stored in a primary winding of a power transformer during energy store cycles by causing a current to flow in the primary winding. This current is interrupted and the stored energy is delivered across the transformer to the load during an energy transfer cycle. The converter includes means for sensing the current in the primary winding at low voltage potentials, and for controlling the duration of each energy store cycle in response to the level of current in the primary winding to deliver the power required to drive the load at the regulated voltages.
