Abstract: A wave energy device converts the motion of waves on a body of water into a usable form of energy, for example a flow of pressurized water or an electrical current. The device includes a buoyant body for tracking the rise and fall of the wave and a working surface coupled for movement with the buoyant body and which is designed to capture and convert both heave and surge forces of the waves. The device includes a rapid deployment and retrieval capability and a capability to rotate to accommodate changes in wave direction. The device is universally attached to the sea floor, wich allows the device to pitch, yaw and roll with the wave forces from any direction, thereby reducing the likelihood of damage due to extreme weather or damage to or from marine traffic in the event of an encounter.

When switching communication operations from a WLAN coverage region of the WLAN to a WWAN coverage region of the WWAN, the mobile device causes a message for forwarding voice calls to a WWAN identification number of the mobile device to be transmitted through the WLAN. The mobile device subsequently causes a message for cancelling the forwarding of voice calls to a WLAN identification number of the mobile device to be transmitted through the WWAN. When switching communication operations from the WWAN coverage region of the WWAN to the WLAN coverage region of the WLAN, the mobile device causes a message for forwarding voice calls to the WLAN identification number of the mobile device to be transmitted through the WWAN. The mobile device subsequently causes a message for cancelling the forwarding of voice calls to the WWAN telephone number of the mobile device to be transmitted through the WLAN.

Abstract: An apparatus is shown for attachment to a plumbing system for the rapid on-demand delivery of hot water through the plumbing system to an ultimate point of use. The apparatus includes a diverter valve located in a hot water supply line upstream of the point of use. The diverter valve is actuated for a predetermined interval by a user to initially purge cold water from the hot water line to a drain. After the preset interval, the valve automatically closes. The initial diversion of cold water standing in the water supply line causes rapid delivery of hot water to the point of use once the diverter valve has completed its cycle.

Abstract: A ballast (10) for powering a lamp load (70) comprising one or more gas discharge lamps (72,74) includes an inverter (200), a resonant output circuit (400), and a control circuit (600). During operation of ballast (10), control circuit (600) monitors at least one voltage within one or more series resonant circuits of output circuit (400). When the monitored voltage reaches a specified level, control circuit (600) directs inverter (200) to maintain its operating frequency at a present value for a predetermined period of time, so as to allow output circuit (400) to provide a suitably high voltage for igniting the lamp(s). If the lamp(s) ignite within the predetermined period of time, control circuit (600) ceases controlling inverter (200) to maintain its operating frequency at the present value, so as to allow for normal operation of the lamp(s). Control circuit (600) also provides a lamp stabilization function, in which the inverter operating frequency is prevented from falling below a specified minimum value, and a protective function, in which inverter (200) is deactivated in response to failure of the lamp(s) to ignite within the predetermined period of time.

Title: Filled, baked crispy snack having a high moisture content
Inventor: KINO JOHN ALAN
IPC: A23L7/10
Filed: 2009-02-23
Granted: 2016-06-14
Abstract: A shelf-stable, filled, baked crispy snack which possesses a crispy textured casing and a moist, soft textured filling over a prolonged period of time is obtained by formulating a casing which when baked has a high glass temperature (Tg) at a high moisture content. Increasing the degree of starch gelatinization to increase the Tg may be achieved during baking and by the addition of a pregelatinized starch. The high Tg baked casing permits the use of a high moisture content filler in high amounts to provide a shelf-stable substantial textural dichotomy in the filled, baked, crispy snack. The filled, baked snack exhibits an unexpectedly high resistance to deformation or peak force at high baked casing moisture contents. The baked snack is ready-to-eat out of the packaging and does not have to be toasted, microwaved or further baked, cooked, or heated for consumption, or to achieve a crisp textured casing.
