  • Patent number: 8511347
    Abstract: A system and method for installing and removing a flow restrictor assembly in a shower, while prevents tampering with the flow restriction system thus installed. Tampering is prevented by concealing the flow restrictor assembly behind a shower wall, attached directly to a water supply line. The system further prevents tampering by concealing the tool-hole necessary for its removal behind a flow restrictor disk, so that there are no visible means of removing the flow restrictor assembly. The flow restrictor assembly threads onto a showerhead arm and the flow restrictor assembly with the attached showerhead arm threads directly into the water line. When the showerhead arm is unthreaded, the flow restrictor assembly remains connected to the water line by an external screw thread. The flow restrictor must be removed to reveal the tool-hole which may only then be engaged by a tool for removal.

  • Patent number: 8496040
    Abstract: An adjustable cord restraining device for a blind assembly having a head rail, a bottom rail and at least one pull cord extending through a cord passage of the head rail and coupled to the bottom rail includes an annular member sufficiently sized to prevent entry of the annular member into the cord passage of the head rail and further travel of the pull cord through the head rail. A method of preventing the further extension of a pull cord includes obtaining an annular member sized larger than a pull cord passageway of a head rail pinching a mid-section of the pull cord and inserting the pinched portion of the mid-section through the annular member, forming a loop with the pull cord, inserting a free end of the pull cord through the loop to form an adjustable knot.

  • Publication number: 20130081730
    Abstract: A device and method restricting water flow from a bathroom fixture is provided herewith. A preferred embodiment of the improved flow restrictor assembly comprises a metallic fitting or housing that accommodates an interior ring assembly and a flow-restrictor disk. The fitting is substantially tubular with a top section, a bottom section and an intersection. The top section of the fitting is defined by an opening, a hollow interior and a ledge upon which the interior ring assembly and flow-restrictor disk are positioned when the flow restrictor assembly is installed and in use. The bottom section features a pair of gripping planes which can be gripped by a specialized tool for purposes of uninstalling the improved flow restrictor assembly.

  • Publication number: 20120287924
    Abstract: A method for telephony includes receiving at an Internet telephony service provider a subscriber request to place a call to a telephone number. A cache associated with the internet telephony service provider is queried to check if the cache holds a record for the telephone number. If the cache holds the record, the record is obtained. If the cache does not hold the record, a request is sent to a database server that maintains a database of records associating endpoint user terminal telephone numbers of subscribers with respective packet network addresses of the endpoint user terminal. The call is placed to the endpoint user terminal telephone number via a public switched telephone network whilst the request is sent to the database server to retrieve the packet network address of the endpoint user terminal to which calls to the telephone number should be placed.

  • Patent number: 8254278
    Abstract: A method for telephony includes receiving at a facility of a telephone service provider a first subscriber request to place a first call to a specified telephone number. A provider request is sent to a remote server (26), which maintains a database (28) of records associating telephone numbers with respective packet network addresses, for a record (72) indicating a packet network address to which calls to the specified telephone number should be placed. Upon receiving the record from the remote server, the record is stored in a local cache (42) at the facility of the telephone service provider. After storing the record, upon receiving at the facility of the telephone service provider a second subscriber request to place a second call to the specified telephone number, the record is read from the local cache and is used in placing the second call to the packet network address.

  • Patent number: 8204924
    Abstract: A method and apparatus are presented for performing wavelet transforms, post transform processing and inverse wavelet transforms whereby hardware complexity is reduced and processor performance is enhanced by performing the forward and inverse wavelet transformations and post transform processing in variable precision arithmetic. Optimal decreases in the operational arithmetic precision of different wavelet scale coefficients, multiplication and weighting operations, and other operations, results in reduced computational complexity, increased speed, and in some cases better signal to noise ratios.
