  • Publication number: 20040061780
    Abstract: A solid-state video surveillance system includes at least two video cameras and a video controller unit. The video controller unit synchronizes the operation of the video cameras such that video data may be independently generated from each of the cameras substantially in phase. The video data from each of the cameras may be merged and stored in a data file. The data file is a continuous loop such that newly stored video data continuously overwrites the oldest previously stored video data. The data file may be stored in a detachable solid state memory device.

  • Patent number: 6698178
    Abstract: A sand trap rake and storage apparatus, wherein a tubular storage compartment is sized to receive the sand trap rake therein. The tubular storage compartment is buried in the ground near a sand trap, so that the open top of the storage unit is above ground. A cover secures the sand trap rake in the tubular storage compartment. A compression spring pushes the rake above the top portion of the tubular storage unit for ease of access. The sand trap rake includes a head pivotally attached to the handle. A hand knob tightens the head against the handle in a first operating position perpendicular to the handle, and the hand knob is loosened to position the head in a second storage position parallel to the handle.

  • Patent number: 6102935
    Abstract: A baby or infant pacifier is disclosed with a sound activated locator annunciator. Comprised of a nipple and associated components utilized on conventional pacifiers, the disclosed apparatus also utilizes a microphone and associated electronic circuitry to monitor for distinctive sound waveforms, such as the clapping of hands, that would normally be minimally found in an infant's or baby's immediate environment. When such a distinctive waveform is detected by the use of fuzzy logic, a speaker emits an audible locator signal, such as a musical tune or sound, for a predetermined time period to allow for location of the apparatus. It is intended that this audible locator signal will aid the care provider of the infant or baby in locating the pacifier when lost.
