摘要:
An optical accelerometer and method of determining an acceleration are disclosed. In one aspect, an accelerometer includes a light source, a substrate, a light guide attached to a first side of the substrate and configured to redirect light from the light source through the substrate. The accelerometer also includes a light detector, a proof mass attached to a second side of the substrate via one or more springs, wherein the second side is opposite the first side and wherein motion of the proof mass alters a characteristic of the light from the light source reaching the light detector, and a processor configured to determine an acceleration based on the characteristic of the light reaching the light detector.

A display with patterned photovoltaic (PV) material integrated on the front side and/or back side of the display is disclosed. Light may reach PV material situated behind a display through fully or partially transmissive features or gaps within the display. Display-generated light may also reach PV material behind a display. A patterned PV material situated in front of a display may collect both ambient light as well as display-generated light.

An interferometric modulator (“IMOD”) display utilizes ambient light and incorporates touch sensing without reducing the amount of ambient light that reaches the MEMS modulators, and without introducing any optical distortion or loss of performance. Electrodes for touch sensing are located at a back glass of the inteferometric display, and are used in conjunction with electrodes whose primary function is to activate the pixels of the MEMS display, in order to sense a touch. The touch deflects the IMOD layers and is sensed through the various display layers at the rear of the display.

A lensless camera may include an array of MEMS-based light-modulating devices. A camera controller may control the MEMS-based light-modulating devices to transmit visible light through, or substantially prevent the transmission of visible light through, predetermined areas of the array. The array may be controlled in response to input from a user and/or in response to the location of a detected subject. The viewing direction of a lensless camera having such an array can be rapidly changed by changing the transmittance of different regions of the array.

A method for coupling a prosthesis to a spinal segment in a patient includes the steps of selecting first and second reference points disposed along the spinal segment and pre-operatively measuring a target distance. The target distance extends between the first and second reference points while the patient is in a preferred posture such as the standing position. A prosthesis is coupled to the spinal segment and the prosthesis is then intra-operatively adjusted in order to set the distance between the first and second reference points based on the target distance.

Methods of manufacturing light panels having at least one re-entrant turning feature. In one embodiment, a method of manufacturing a light panel includes providing a base layer, providing a cover layer, and coupling the cover layer to the base layer to form at least one re-entrant turning feature between the base layer and the cover layer. In another embodiment, a method of manufacturing a light panel includes providing a base layer, forming at least one receiving space in the base layer, providing at least one prismatic block, and coupling at least a portion of the prismatic block into the receiving space such that re-entrant turning features are formed between the prismatic block and the base layer.
摘要:
Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.

Some embodiments comprise at least one array that includes microelectromechanical systems (“MEMS”)-based light-modulating devices. Elements of the array(s) may be configured to absorb and/or reflect light when in a first configuration and to transmit light when in a second position. Such an array may be controlled to function as a camera aperture and/or as a camera shutter. For example, a controller may cause the array to function as a shutter by causing the MEMS devices to open for a predetermined period of time. The predetermined period of time may be based, at least in part, on input received from a user, the intensity of ambient light, the intensity of a flash, the size of the camera aperture, etc. Some embodiments provide a variable aperture device that does not add significant thickness or cost to a camera module. Such embodiments may enable a camera to function well in both bright and dark light, to control depth of field, etc.

The color reflected by an interferometric modulator may vary as a function of the angle of view. A range of colors are thus viewable by rotating the interferometric modulator relative to an observer. By placing a textured layer between an observer and an interferometric modulator, a pattern which includes the range of colors may be viewed by the observer, and the range of colors may thus be viewable from a single viewing angle.

A system for restricting spinal flexion includes superior and inferior tether structures joined by a pair of compliance members. Compliance members comprise tension members which apply a relatively low elastic tension on the tether structures. By placing the tether structures on or over adjacent spinous processes, flexion of a spinal segment can be controlled in order to reduce pain.
