Abstract:
A photodetecting unit having a favorable attaching operability is provided.In a photodetecting unit 1, two structures for attachment 30 are fixed to the rear face of a supporting substrate 20 formed by a sintered body of a ceramic. In the process of manufacturing the photodetecting unit 1, a laminate of green sheets is fired, so as to form a sintered body of a ceramic, and then each structure for attachment 30 is bonded to the rear face of the supporting substrate 20. This allows the structures for attachment 30 to be arranged accurately on the rear face of the supporting substrate 20, thereby ameliorating the attaching operability of the photodetecting unit 1.
Abstract:
An optical sensor for detecting motion or movement in an area of interest and a method of operation is provided. The system includes a CMOS sensor having an array of pixels that captures images in an area of interest. The system monitors the average pixel value for the array to define a first state. If the average pixel value changes beyond a defined threshold, the system defines a second state. For each change in state, a signal is generated. In one embodiment, the optical sensor is used with a meter having a dial with an indicator. The optical sensor generates a signal each time the indicator passes through the area of interest to allow for the remote monitoring of a consumable commodity.

An optical transceiver includes at least one light source and at least one detector mounted on the same surface of the same substrate. The detector is to receive light from other than a light source on the surface. At least one of the light source and the detector is mounted on the surface. An optics block having optical elements for each light source and detectors is attached via a vertical spacer to the substrate. Electrical interconnections for the light source and the detector are accessible from the same surface of the substrate with the optics block attached thereto. One of the light source and the detector may be monolithically integrated into the substrate.
Abstract:
A method for measuring the luminance of a light-emitting object having a surface which has a definite area and which emits a low-intensity light and a device therefore, wherein a light-receiving surface of an optical sensor is brought into direct contact with the surface of the light-emitting object to measure the luminance thereof. As the optical sensor, a semiconductor sensor panel or, a solar panel is preferably used. The luminance of a light-emitting object which emits a low-intensity light can be measured simply, easily and properly without a darkroom and without a means such as a light condensing lens system which is complicated and difficult to use.
Abstract:
A small infrared sensor has a wide infrared light-receiving area (viewing angle), high electromagnetic shielding characteristics, and excellent electromagnetic-wave resistance characteristics. In the infrared sensor, supporting portions are disposed at four corners of a substantially rectangular opening in a package. The supporting portions support an optical filter, disposed so as to cover the opening, at positions that are lower than an upper end of an inner peripheral wall defining the opening. While the optical filter is supported by the supporting portions as a result of inserting a portion of a surface side of the optical filter facing the supporting portions into the opening, the optical filter is secured to the package. The optical filter and the package are joined and secured, and electrically connected to each other through a conductive adhesive.

Abstract:
Eyewear having radiation monitoring capability is disclosed. Radiation, such as ultraviolet (UV) radiation, infrared (IR) radiation or light, can be measured by a detector. The measured radiation can then be used in providing radiation-related information to a user of the eyewear. Advantageously, the user of the eyewear is able to easily monitor their exposure to radiation.
Abstract:

A light source control device has a light detection device for detecting emission brightness of light sources that emit different colors and controlling emission brightness of at least one light source of the light sources based on the detection result of the light detection device. A through-hole is formed in a reflection member for reflecting light emitted from the light source, and the reflection is in a predetermined direction. The light detection device is provided across the reflection member from the light source, and the light propagation member is provided at the through-hole.
Abstract:
Systems and methods are provided for depositing solder in a first pattern over a first bonding pad on the substrate; depositing solder in a second pattern over a second bonding pad on the substrate, wherein the second pattern defines a larger area than the first pattern; placing the electronic device on the substrate such that pads on the electronic device are aligned with the first and second bonding pads; and reflowing the solder between the pads on the electronic device and the first and second bonding pads, causing the solder deposited on the first bonding pad to form a first solder joint and the solder deposited on the second bonding pad to form a second solder joint. The second solder joint is larger than the first solder joint causing the electronic device to be attached at an angle relative to the substrate.
