摘要:
The invention relates to a method for the fabrication of composite palladium or palladium alloy membranes. The surface of the porous ceramic substrate is modified with pencil to create a uniform and smooth layer, and the membrane is deposited via electroless plating. The advantages of the pencil modification are a reduction of the substrate surface roughness and a repair of substrate surface defects, which leads to a great improvement in the membrane uniformity and hydrogen permeation performances. This method is facile and economic, and it is especially effective on low-cost macroporous ceramic substrate materials. Furthermore, this method generates almost no pollution and therefore is environmentally benign.

摘要:
A touch sensor interface includes one or more touch detection electrodes whose capacitance increases when touched. A processor converts the increase in capacitance into a change in a counter value. A detector compares the change in the counter value with one or more count thresholds to detect faults in the touch sensor interface.

A method and apparatus for providing quality of service over a contention access period of a wireless personal area network is provided herein. Particularly, the layers above the MAC are allowed to reserve portions of a contention access period (CAP) in order to schedule their QoS actions cooperatively thereby avoiding the dependence on the MAC for QoS performance. By using cooperative scheduling, a node can send a QoS packet from the QoS_Layer to the MAC, and know that it will be transmitted according to the specified QoS requirement. As a result, whenever a node sends a QoS packet in the reserved portion of the CAP, the channel will be guaranteed to be free from competing nodes' packets because those competing nodes will delay their transmissions based on the shared schedule.

A drug delivery device for placement in the eye includes a drug core comprising a hydrophobic pharmaceutically active agent, and a holder that holds the drug core. The holder is made of a material impermeable to passage of the active agent and includes an opening for passage of the pharmaceutically agent therethrough to eye tissue. The device includes polyurethane-siloxane-containing copolymers crosslinked with hydrophilic monomers.

A semiconductor light emitting device for emission of light having a predetermined bandwidth in a primary direction of emission includes a light generating region for the generation of light; and a 1-dimensional photonic crystal structure having a photonic bandgap covering at least a segment of said bandwidth. The 1-dimensional photonic crystal structure is located such that upon incident of light from the light generating region, light having a wavelength within the bandgap of the 1-dimensional photonic crystal structure is reflected in the primary direction of emission.
摘要:
An ad-hoc communication system is established where each node within the system may have multiple children nodes and parent nodes. An address scheme is proposed where each node may comprise more than one address, each address being based upon one of the parent's address. Because each node may have more than one parent, a bridge, or shortcut may exist between network branches.

In order to discover neighboring nodes (203, 207, 208) within a particular piconet, a first node (206) determines a list of all nodes (205-207) within its piconet (201) and then transmits to each node within the piconet, a message requiring a response. Depending upon which nodes are heard from, a list is formulated by the first node comprising those nodes neighboring the first node. In order for neighboring nodes within other piconets to “discover” the first node, the first node will also scan its environment to determine piconet identifications for other piconets, and then broadcast a “discovery” message having a piconet identification of a neighboring piconet. In a similar manner, the first node will also scan its environment to determine discovery messages transmitted by other nodes, thus determining neighboring nodes outside its piconet.
