  • Patent number: 6980100
    Abstract: A security device and alarm system includes a reader preferably concealed in a fabric article, at least one tag, and an alarm unit. The reader includes a reader transmitter, reader receiver, CPU, power source, and power switch. The tag includes a tag transmitter and a tag receiver. If using active RFID tags, each tag includes a power source. The alarm unit includes an alarm receiver, alarm, and power source. If the reader receiver does not receive an appropriate reply from the tag transmitter after the reader transmitter sends a query to the tag receiver, or if the reader was deactivated, the reader transmitter sends an alarm signal to the alarm unit. Upon the alarm receiver's receipt of the alarm signal, the alarm is energized. If using multiple active RFID tags, the CPU checks for each through tag transmission identifiers, and the alarm identifies the missing tag through unique alarm signals.

  • Patent number: 6899371
    Abstract: An auxiliary sun visor for a vehicle sun visor comprises an auxiliary sun visor panel, a pair of opposed clips, a track assembly defining a first axis attached to the clips, and a mount for attaching the visor panel to the track assembly and for permitting pivotal movement of the panel about the first axis and a second axis transverse to the first axis. The clips are configured for coupling the auxiliary visor to a vehicle sun visor. The track assembly and mount cooperably permit the pivotal movement of the panel about the first axis. The mount may be selectively positioned along the track assembly in order to move the position of the second axis relative to the first axis.

  • Patent number: 6686840
    Abstract: A personal security alarm system includes transmission and alarm housings. The transmission housing includes a transmitter connected to control buttons for selectively sending alarm or range signals. The alarm housing includes a receiver, CPU, alarm, and a mode switch. In automatic mode, the receiver receives continuous range signals from the transmitter and the CPU energizes the alarm if the range signals are not received. In alarm mode, the CPU energizes the alarm if the receiver receives a predetermined alarm signal. The alarm housing may be coupled to a quick-connect attachment of a purse. The purse includes an electro-mechanical locking assembly that may be energized by the CPU. The purse may be locked upon a sensed theft attempt or by a user pressing a control button on the alarm housing.
