Hand pressure sensor warning device
First Claim
1. A hand pressure sensor warning device for use with hand held objects including sports devices, steering devices, writing devices, and computer interface devices, and for generating an alarm signal when the hand or finger pressure being applied to said warning device exceeds a threshold value, said device comprising:
- a normally open electrical membrane switch having a first and a second membrane layer, each membrane layer having electrical contact areas including electrically conductive material;
an electrical indicator electrically connected to said electrical membrane switch and having a power supply;
an alarm signal device electrically connected to said electrical indicator for generating an alarm signal; and
a housing to enclose said electrical membrane switch, said electrical indicator, and said alarm signal device, a portion of said housing lying in close contact with the membrane switch, whereby the alarm signal device generates an alarm signal when the membrane switch is closed by means of hand or finger pressure applied to the portion of said housing which lies in close contact with said membrane switch.

Abstract
An ergonomic lightweight hand pressure sensor-warning device for use with hand held objects like sport devices, steering devices, writing devices or computer devices, as well as the method for its assembly. This new hand pressure sensor warning device is designed as a relatively thin plaster/band-aid to attach the device onto the outside surface of the handgrips of hand held devices like a golf club, making the attachment to and detachment from the hand held device very simple and user-friendly. The device contains an electrical membrane switch, an electrical indicator with an alarm device and a streamlined oblong housing element which contains the principal components in a compact unit. Due to its low manufacturing costs, the warning device is also highly attractive as a commercial advertising product and as a corporate gift or premium product. The unintended and unexpected detachment of the device during a golf swing is practically impossible.

- 13. A membrane switch for use in a hand pressure sensor warning device and comprising a first membrane layer having first and second electrical contact areas which are spaced from one another to establish an open electrical switch circuit, a second membrane layer having third electrical contact areas spaced from and aligned with the first and second electrical contact areas of said first membrane layer to close the electrical switch circuit on the first membrane layer when a hand or finger pressure is exerted on the membrane switch which exceeds a threshold value, an alarm signal device electrically connected to the first and second electrical contact areas of said first membrane layer and adapted to generate an alarm signal when the electrical switch circuit on the first membrane layer is closed, and a power supply to provide power to said alarm signal device when said electrical switch circuit is closed.
