摘要:
An apparatus and method for integrating an indicator light in a connecter assembly. A connecter is mounted on a first side of the circuit board and an LED is mounted on an opposing side of the circuit board such that the LED is configured to project light through a light transfer passage into the interior of the connecter on the first side of the circuit board. The LED can be used to provide a visual indication of a configuration or status of a circuit associated with the connecter. The visual indication illuminates the interior surface of the connecter when it is empty or illuminates a light transmissible plug inserted into the connecter such that the visual indication is visible external to the connecter. The novel arrangement can reduce manufacturing costs and permit easier replacement of a defective LED without requiring the removal of the connecter.

A dental bur structure including a rotatable shaft turned by a motor. The shaft possesses a proximal portion having a fluted surface. The bur also possesses a distal portion with a smooth surface tip which generates heat to melt a composite post matrix upon activation of the shaft. The fluted surface removes a composite material while the smooth tip serves as a guide for the bur.

The present invention proposes to apply against dangerous natural phenomena (mainly hurricane) relocatable water pump stations using wave energy and having two states: operating state (for cold water pumping) and collapsed state (suitable for transportation). In collapsed state these stations have a severe less cross-section at least in one of horizontal directions. Such stations include reconfiguration means for theirs transforming from one said state to the second state and back.

An architecture for developing a distributed information system comprises a service definition tool for generating service protocols as a service definition. Each service protocol includes a plurality of messages. The messages include incoming messages and outgoing messages. Each message carries a plurality of data fields. A component development tool generates a first and second plurality of components that implement and consume services. Each component in the first plurality of components represents a physical entity in the distributed information system. Each component in the second plurality of components represents a logical entity in the distributed information system. A system development tool generates a plurality of component instances based on the first and second plurality of components. An engine software program runs on each of a plurality of networked nodes. The engine software program provides a programmable run-time environment for hosting the plurality of component instances and supporting communication between component instances.

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.
摘要:
A beam homogenizer that minimizes undesired intensity variations at the output plane caused by sharp breaks between facets in previous embodiments. The homogenizer includes a hologram made up of irregularly patterned diffractive fringes. An input beam illuminates at least part of the hologram. The hologram transmits a portion of the input beam onto an output plane. In doing so, the energy of the input beam is spatially redistributed at the output plane into a homogenized output beam having a preselected spatial energy distribution at the output plane. Thus, the illuminated portion of the output plane has a shape predetermined by the designer of the homogenizer.

A thin camera having sub-pixel resolution includes an array of micro-cameras. Each micro-camera includes a lens, a plurality of sensors of size p, and a plurality of macro-pixels of size d having a feature of size q. The feature size q smaller than p and provides a resolution for the micro-camera greater than p. The smallest feature in the micro-cameras determines the resolution of the thin camera. Each macro-pixel may have any array of m features of size q, where q=d/m. Additional micro-cameras may be included to increase power.

摘要:
Integrated multiple optical elements may be formed by bonding substrates containing such optical elements together or by providing optical elements on either side of the wafer substrate. The wafer is subsequently diced to obtain the individual units themselves. The optical elements may be formed lithographically, directly, or using a lithographically generated master to emboss the elements. Alignment features facilitate the efficient production of such integrated multiple optical elements, as well as post creation processing thereof on the wafer level.
摘要:
An intraosseous delivery apparatus having a drilling member and a sleeve member. The drilling member includes a drill housing, a connecting portion for establishing a connection to a conventional dental drilling apparatus, and a drill extending from the drill housing. The sleeve member includes a sleeve housing, and a hollow sleeve extending from the sleeve housing. The sleeve housing is adapted to be removably engaged with the drill housing such that the drill is inserted into the hollow sleeve. The drill has a length such that when the drill is inserted into the hollow sleeve, a portion of the drill extends beyond the hollow sleeve. As a result, when the drill is used to drill a hole in bone, the drill is inserted deeper into the hole than the hollow sleeve. The hollow sleeve is adapted to be left inserted in the bone when the drill is removed therefrom. The “in place” hollow sleeve is also adapted to receive a syringe needle through which anesthesia may be directly introduced into the bone via an exposed bottom portion of the drilled hole as well as via exposed side-wall portions of the drilled hole. The drill is preferably smooth, and may also be hollow so that debris generated during drilling enters the interior of the drill. In this case, when the hollow drill is removed from the hollow sleeve, the debris within the hollow drill may also be removed
