Gesture based electronic latch for laptop computers

摘要

A portable information handling system includes a top cover, a base, and an electronic latch. The top cover is connected to the base. The top cover has a gesture sensitive surface configured to receive a trace. The electronic latch is in communication with the gesture sensitive surface, and is configured to latch the top cover and the base together. The electronic latch is further configured to unlatch the top cover from the base in response to receiving a signal representing that the trace received on the gesture sensitive surface is proper.

主权项

1. A portable information handling system for performing various computing functions, comprising:
a base having a front portion, a back portion, a left portion, a right portion, and a bottom portion; a top cover connected to and covering the back portion of the base, the top cover having a gesture sensitive surface and a plurality of light emitting diodes, the gesture sensitive surface configured to receive a trace, wherein the trace is a movement of a finger of a user across the gesture sensitive surface, and the light emitting diodes are configured to provide a visual indication that the trace was proper, wherein the visual indication is the light emitting diodes lighting up one by one in a direction that the finger of the user is swiped across the gesture sensitive surface based on a current location of the finger on the gesture sensitive surface; and a processor in communication with the gesture sensitive surface, the processor configured to receive a signal associated with the trace from the gesture sensitive surface, and to determine whether the trace is proper; an electronic latch in communication with the processor, the electronic latch configured to latch the top cover around the entire front portion, the entire left portion, and the entire right portion of the base wherein only the top cover and the bottom portion of the base are visible when the portable information handling system is closed, wherein the electronic latch including:
a catch portion located within the base; anda coil and a hook portion located within a recess of the top cover; wherein the hook portion is located within the coil and the coil is configured to receive an unlock signal from the processor representing that the trace received on the gesture sensitive surface is proper, and to create a magnetic field in response to the unlock signal, the magnetic field is configured to pull the hook portion from the catch portion to unlatch the top cover from the base in response to receiving the unlock signal from the processor representing that the trace received on the gesture sensitive surface is proper, wherein a spring loaded mechanism between the top cover and the base is configured to cause the top cover to separate slightly from the base in response to the electronic latch being unlocked.
