Tamper-alert and tamper-resistant band

摘要

A tamper alert band includes a housing, a latch, and a latch-blocking member. The latch is configured to move between at least an unsecured position and a secured position, in the unsecured position first and second housing elements are movable with respect to each other and in the secured position the latch secured the first housing element with the second housing element. The latch-blocking member is controllably moveable between at least a first position and a second position, the blocking member being moveable to the first position when the latch is in the secured position to thereafter obstruct movement of the latch to the unsecured position.

主权项

1. A band adapted for affixation around a human extremity, said band comprising:
a housing that includes a first housing element and a second housing element; a wireless transceiver disposed in the housing and configured to wirelessly communicate with at least one remote computing node; a latch disposed in the housing and configured to move between at least an unsecured position and a secured position, in the unsecured position the first and second housing elements being movable with respect to each other, in the secured position the first and second housing elements being restrained from movement with respect to each other; a blocking member disposed in the housing and controllably moveable between at least a first position and a second position, the blocking member being moveable to the first position when the latch is in the secured position to obstruct movement of the latch to the unsecured position; an electric motor disposed in the housing and configured to move the blocking member from the first position to the second position and from the second position to the first position, electric motor is configured to rotate the blocking member from the first position to the second position and from the second position to the first position; and data processing circuitry coupled to the wireless transceiver and to the electronic motor, the data processing circuitry being configured:
to determine that the blocking member is in at least one of the first and second positions;to cause the electric motor to controllably move the blocking member from the first position to the second position based on determining that the blocking member is in the first position; andto cause the electric motor to controllably move the blocking member from the second position to the first position based on determining that the blocking member is in the first position.
