International Classification:

A42B 1/24

US Classification:

2422, 2410

Abstract:

An electronic helmet is provided that includes a helmet body and an integrated electronic system disposed in the helmet body, providing a number of convenient functions. The helmet body has a hard outer shell and a hard inner shell mounted to the outer shell such that a cavity is defined between the outer and the inner shells. The inner shell can include suitable material to provide the wearer effective RF shielding from the electronic system, such as, nickel-plated carbon fiber to provide RF shielding. The helmet body further includes a shock-absorbent structure disposed between the inner shell and the head of a wearer.

Jun 20, 1983

Appl. No.:

6/505902

Inventors:

Daniel R. Emmons - San Diego CA
William E. Swanson - San Diego CA

Assignee:

GTI Corporation - San Diego CA

International Classification:

G06F 752

US Classification:

364736

Abstract:

A cross product calculator to multiply mathematical representations of a pair of vectors in order to calculate a resultant vector, which resultant vector is aligned normal to the plane in which the pair of vectors is located. The present cross product calculator has application to a real time computer generated imagery or graphics system having the capability to provide reliable color shading of a three dimensional object moving across the screen of a video display. The resultant normal vector provided by the cross product calculator is indicative of the orientation of the object relative to a source of supply of incident light. Storage apparatus and control hardware are included to provide accurate, normalized equivalents of the mathematical representations of the pair of vectors which are multiplied together to derive the cross product thereof. More particularly, a plurality of multiple bit data strings, representing intermediate products of the pair of vectors, are reduced in size without suffering a corresponding loss of information content, so that the resultant cross product (i. e. normal vector) can be calculated with increased speed and minimized data storage requirements.

International Classification:

G06F 500

US Classification:

364715

Abstract:

A matrix multiplier having application to a real time computer-generated imagery or graphics system, wherein the output of the multiplier is normalized to increase both the accuracy and speed by which a three dimensional object can be displayed on a video stream. The output of the matrix multiplier is typically a plurality of multiple (e. g. 32 or more) bit serial data screen. Each data stream is normalized to itself and to each of the other of the plurality of data streams which form the product of the matrix multiplication. That is, a particular segment (e. g. 16 bits) of each data stream is selected for continued processing in order to efficiently and accurately define an object in three dimensional space. The selection of each data stream segment is dependent upon the bit pattern thereof and, more particularly, upon the occurance of a pair of successive bits of opposite polarity relative to one another. Accordingly, in the event that many streams of data contain respective bit patterns wherein a large number of the most significant bits are all of the same polarity, the data streams are normalized or shifted by an identical number of bit positions, wherein some of the most significant bits thereof are discarded while the lesser significant bits are retained.

International Classification:

A61B 5/00
A61B 5/1455
A41D 20/00
A61B 5/0205
A61B 5/01

Abstract:

A headwear assembly is disclosed having an oximetry sensor and a circuit assembly configured to measure pulse and oxygen level for a user during exercise and/or physical activity. The oximetry sensor is positioned in a front section of the headwear assembly, proximate to the forehead when worn. Other sensors can also be included with the headwear assembly, such as temperature, blood pressure, and so on. The headwear assembly is configured to securely conform about a user's head when worn, such that the oximetry sensor is positioned and effectively immobilized on the forehead above the eyebrows. The headwear assembly can further provide integrated functionality with an external electronic device, such as a smart mobile phone. The headwear assembly can include a wireless charger for charging a rechargeable battery disposed on the headwear assembly.
