Title: Diverter assembly with integral water-hammer arrestor
Inventor: BAILEY ROBERT W
IPC: F16L55/04
Filed: 2004-01-29
Abstract: A faucet diverter assembly for dampening a pressure spike includes a body and a diverter bonnet assembled into the body defining a flow passageway therebetween. A diverter portion is assembled into the diverter bonnet and is axially movable by the use of an extender. The diverter portion includes and upper stem and a lower stem attached to the upper stem. Assembled onto the lower stem is a movable plunger that is spring biased by a spring positioned between the plunger and the upper stem. A return spring, received by the upper stem, acts between the upper stem and the diverter bonnet. When a pressure spike is encountered, the pressure force is sensed by the plunger by way of a flow inlet passage and movement of the plunger, in response to the pressure force, compresses the plunger spring, thereby functioning as a shock absorber.

Filed: 2004-06-02
Abstract: The present invention relates to a unique digital video capturing device primarily intended for automotive use. The device is unique in that it is constantly recording one or more video signals, while external power is applied from the vehicle's power.  The recording is terminated by an internal impact switch, or by manually depressing a stop switch. Activation of either trigger device will cause the recording to continue for a predetermined amount of time and then automatically stop, saving the complete loop of video data to non-volatile memory. The device has provisions for a removable solid state media chip, as well as an internal non-removable memory chip. Internal back-up power is provided, in the event of a collision that disabled vehicle power. In integrated version could be built into the vehicle's interior rear-view mirror, and be powered through the ignition switch. Video capture can occur from a forward facing sensor or a pair of opposing sensors for an expanded view.

Abstract: Systems, methods and computer program operating on a computer that integrates as an add-on with software based day/time planners and calendars then notifies the users using speech synthesis by telephone (mobile or landline) of reminders and appointments at the appropriate date and time based on what the users have preset and registered as upcoming reminders (reoccurring or not). Sending a facsimile, text messaging on a mobile telephone or a hand-held organizer (using SMS), voice synthesis on loudspeakers, text pager, PDA, or emailing reminders in text or HTML format could also achieve the notification or any combination of these methods. Equally, the system could allow the users to dial-in, using either voice commands by performing speech recognition or accepting dial tones when the users press the telephone's keypad and performing commands to check for upcoming reminders, add, delete or edit reminders as well as direct the system as to how it should deliver back its responses and reminders. Alternately, the users may electronically send the system emails with embedded commands, to which the system may periodically check for, in order to allow the same kind of remote control.
