Abstract:
A method for forming an image sensor assembly includes forming a lead frame or Land Grid Array (LGA) integrally into a molded image sensor die package so that the lead frame or LGA is fully supported and structurally fortified by the molded image sensor die package. An image sensor die is then attached to the thus supported lead frame or LGA using a standard flip-chip connection.
Abstract:
A digital image capture system includes an image sensor package and a powered lens element that is attached to the image sensor package. The image sensor package includes an image sensor, a package structure for holding the image sensor, and electrical connectors for creating electrical connection between the image sensor and a circuit board. The package structure and the powered lens element include complementary surfaces that enable the powered lens element to be attached to the image sensor package. Preferably, the powered lens element is glued to the package structure to create a sealed environment for the image sensor. In an embodiment, a temporary protective cover is attached to the powered lens element to protect the powered lens element during attachment of the image sensor package to the circuit board. In an embodiment of the digital image capture system, an additional powered lens element is attached to the powered lens element to create a composite lens element. In an embodiment of the digital image capture system, the powered lens element includes an opaque surface that prevents unwanted light from contacting the image sensor. An advantage of the digital image capture system is that no additional lens mounting structures are required to attach a powered lens element to the image sensor package.

Abstract:
A box load interface implemented in a FIMS system includes a retractable port door that is attachable to the box door of a transport box. The port door selectively moves the box door toward or away from the box cover of the transport box to thereby open or close it. A slidable tray is mounted to a support shelf. The slidable tray includes a clamping mechanism that receives and clamps the transport box in a fixed position on the slidable tray. A positioning mechanism moves the slidable tray to force the box cover against the port plate. The positioning mechanism also retracts from the port plate to release the box cover. A port door translation mechanism is operatively connected to the port door to advance it and retract it toward and away from a port plate aperture. A port door elevator assembly operates in cooperation with the port door translation mechanism to move the port door after the box door has been moved away from the box cover and through the port plate aperture. An alternative embodiment implements the port door translation mechanism and elevator assembly as an integral structure. A differential optical scanning assembly detects positions of wafer specimens located in the transport box. A robot assembly is supported by a linear traveling assembly between adjacent port plate apertures for removing and inserting wafer specimens from the transport box. The linear traveling assembly includes a carriage that supports the robot assembly and that travels along a lead screw between the port plate apertures driven by a lead nut mechanism.
Abstract:
A motor-driven pan-tilt unit such as a pan-tilt camera mount designed to remotely control panning and tilting motion of, for example, a surveillance camera is provided. The pan-tilt unit includes a pan mechanism, a transmitting unit, and an optical signal transmitting unit. The pan mechanism has a stationary housing and a rotary shaft in connection with the camera. The transmitting unit includes a plurality of conductive rings and a plurality of conductive contacts. Each of the conductive rings is mounted on one of the rotary shaft and an inner wall of the stationary housing in electrical contact with one of the conductive contacts to establish transmission of electric power and control signals required for a tilt mechanism and the camera. The optical signal transmitting unit includes a light-emitting element and a light-sensitive element. One of the light-emitting element and the light-sensitive element is attached to an end of the rotary shaft so as to establish transmission of an optical signal from the light-emitting element to the light-sensitive element for transmitting image data from the camera to a signal processing circuit mounted on a stationary part of the pan-tilt unit. The housing defines therewithin a hermetic chamber within which the transmitting unit and the optical signal transmitting unit are disposed, thereby avoiding sticking of dust to the units, for example.
Abstract:
An armored detector assembly, a mining system, and methods of using it are described. The armored detector assembly consists of a main assembly and a hatch assembly. The hatch assembly is welded onto mining equipment, and the main assembly is removably attached to the hatch assembly. The armored detector assembly houses sensitive monitoring equipment used in mining operations. Because of its rugged construction the armored detector assembly is suitable for storing a wide range of sensitive equipment in harsh industrial environments. One embodiment allows for openings in the main assembly so that gamma radiation can enter the main assembly and be measured by gamma radiation monitoring equipment used in continuous mining operations. A portion of the gamma radiation monitoring equipment is enclosed within an integral explosion proof enclosure. This embodiment contains a fluid channel and a plurality of spray orifices to reduce the risk of ignition of dust or gas and other orifices for removal of mining debris from the openings in the assembly.

An electronic part is, for example, a double molded photo-interrupter. The photo-interrupter incorporates a light emitting device and a light receiving device which are encapsulated with a light-transmitting resin. The two devices are packaged into one body with an opaque synthetic resin in such a way as to be opposed to each other. A through-hole is formed through the resin package and hooks extended downward from the bottom face of the package near the through hole are integrally formed with the package.
Abstract:
An infrared receiver mount is disclosed that is capable of directional reception with discrete positions and is applicable for use in a mobile carriage system. An infrared receiver is mounted within a conical section of an outer cover which directs the infrared receiver to receive infrared transmission from a first given angle of reception. The outer cover contains a plurality of grooves, which are engageable with a plurality of tabs located on a base plate to prevent rotation of the infrared receiver. The tab and groove system provides a discrete number of directions for the infrared receiver to receive infrared transmission from a second angle of reception. While this second angle of reception is adjustable, the first angle of reception is predetermined. In one application, the infrared receiver is mounted to the lower portion of a carriage in order to receive light beams from an infrared transmitter. By disengaging the tabs from the grooves, the infrared receiver is rotatable to vary the second angle of reception. This locking mechanism can then be locked into one of a distinct number of directions. The locking mechanism provides more precise placement of the infrared receivers in an optimal receiving orientation and prevents unintentional movement of the infrared receiver from its desired reception position.
Abstract:
A multifunction adapter for use in a motion sensor module holds a lens at the front of the adapter in a predetermined position and distance relative to a sensor mounted on a circuit board, and uses positioning projections at the rear of the adapter to set a predetermined distance of the adapter from the sensor and the circuit board. The adapter can be adjusted to set the focal point of the lens at an optimized position for the sensor. Additionally, a cover that shrouds the sensor is present on the rear side of the adapter for reducing or eliminating air flowing across and around the sensor. When the sensor is a passive infrared device, the reduction in air flowing around and across the sensor reduces the number of false signals.
