摘要:
A flexible and/or stretchable “test data sheet” is provided for recording technical parameters associated with various industrial equipment. The test data sheet includes a flexible and/or stretchable substrate, a microprocessor disposed on the substrate, a memory disposed on the substrate, a power source disposed on the substrate, and one or more sensors of various types disposed on the substrate (e.g., temperature sensors, photodiodes/imaging sensors, impact/force sensors, accelerometers, etc.). The test data sheet optionally may include one or more ports or communication interfaces to facilitate wired or wireless communication to/from the data sheet. The test data sheet is coupled (e.g., applied to) an arbitrarily-shaped surface associated with a piece of industrial equipment, a tool, a pipe, etc., and the test data sheet conforms to as to facilitate intimate proximity to the surface. In this manner, the test data sheet may be in the form of an electronic sticker or decal. The elastic nature of the test data sheet permits it to accommodate vibrations, stretching, change of shape, etc. Of the surface itself, and harsh conditions associated with same, while nonetheless maintaining the data sheet's electronic functionality.
摘要:
Sensing a force and/or a change in motion proximate to an arbitrarily-shaped surface via a conformal sensing element (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate and having a sufficient mechanical coupling to the surface. The conformality of the sensing element facilitates intimate proximity to the surface to ensure accurate sensing. Examples of arbitrarily-shaped surfaces include body parts of a person (e.g., a head). A processor receiving one or more signals from the sensing element may provide information relating to possible injury to a body part (e.g., head trauma) resulting from sensed forces and/or changes in motion. Such information may be conveyed by one or more output devices that provide indications of possible degrees of injury/trauma. A conformal sensing apparatus may be integrated with a protective garment or accessory, such as a helmet, wherein the conformality of the sensing apparatus also ensures sufficient comfort for the wearer.

摘要:
Sensing a change in motion proximate to an arbitrarily-shaped surface via a single sensing element (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate having a sufficient mechanical coupling to the arbitrarily-shaped surface. The change in motion may include at least one of an acceleration, an orientation, a vibration shock and a falling process. In one example, the flexible substrate substantially conforms to the arbitrarily-shaped surface so as to facilitate intimate proximity to the arbitrarily-shaped surface. In another example, a coupling mechanism may mechanically couple the sensing element to the arbitrarily-shaped surface. One or more LEDs coupled to the sensing element may provide a visual cue representing impact or trauma to the surface based on different colors respectively corresponding to a degree of the impact or trauma.

Sensing a change in motion proximate to a body part of a person via one or more sensing elements disposed on a flexible substrate and having a sufficient mechanical coupling to the body part. A proximity of the sensing element(s) to the body part is detected, and power is coupled to or decoupled from the sensing element(s) based at least in part on the detected proximity.
摘要:
Sensing a force and/or a change of motion proximate to a person's head via one or more sensing elements (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate having a sufficient mechanical coupling to the person's head. The conformality of the sensing element facilitates intimate proximity to the surface of the person's head to ensure accurate sensing. A processor receiving one or more signals from the sensing element may provide information relating to possible injury to a body part (e.g., head trauma) resulting from sensed forces and/or changes in motion. Such information may be conveyed by one or more output devices that provide indications of possible degrees of injury/trauma. A conformal sensing apparatus may be integrated with a protective garment or accessory, such as a helmet, wherein the conformality of the sensing apparatus also ensures sufficient comfort for the wearer.
