  • Patent number: 11612027
    Abstract: A multi-spectral flashlight includes a housing, a battery disposed in the housing, a power switch, a LED module including a plurality of LEDs which emit different colors of illumination, a LED driver coupled to the LED module, and an alternate illumination selector switch coupled to the LED driver. The LED driver is configured to drive the LED module in a default illumination mode in response to a first user operation of the power switch and a selected alternate illumination mode in response to a second user operation of the power switch. The LED driver is further configured with a plurality of selectable pre-determined alternate illumination modes which include different colors of illumination. The LED driver advances through the plurality of selectable pre-determined alternate illumination modes in response to operation of the alternate illumination selector switch, allowing selection of one of the plurality of modes as the selected alternate illumination mode.

  • Patent number: 11268304
    Abstract: A disposable, flexible locking restraint having a base and first and second straps integrally molded of a dry flexible plastic is provided. During use, toothed portion of the straps engage toothed portions of associated pawls to provide for unidirectional travel of the straps through the base. For increased security, pawl locks are provided on the base. Each pawl lock has first and second retainers to engage the pawl lock on the base, where the first retainer is spaced from the second retainer along a length of the pawl lock. When the first retainer retains the pawl locks in the base, the pawls have sufficient freedom of movement to allow unidirectional movement of the straps through the base, and when the pawl locks are depressed such that the second retainer retains each pawl lock in its respective lock aperture, the pawl lock engages the pawl and presses the pawl against the strap, preventing further travel of the strap.
