摘要:
A method of growing semiconductor materials in the Indium, Aluminium, Gallium Nitride (InAlGaN) material system and to devices made therefrom, in particular optical devices in the ultraviolet to green region of the visible spectrum. Certain optical devices, for example Vertical Cavity Surface Emitting Lasers (VCSELs) require great precision in the thickness of certain semiconductor layers. One aspect of the present invention provides a gallium-rich group III nitride layer (200, 201) and an adjacent layer of AlxInyGa1-x-yN layer (202). The AlxInyGa1-x-yN layer (202) acts as a fabrication facilitation layer and is selected to provide a good lattice match and high refractive index contrast with the gallium-rich group III nitride layer (200, 201). The high refractive index contrast permits in-situ optical monitoring. The extra layer (202) can be used as an etch marker or etch stop layer in subsequent processing and may be used in a lift-off process.

Various embodiments of a wireless control glove are optimized for use with powered rideable boards, mobility devices, or remote-controlled (RC) models. Incremental, “analog-like” throttle control takes full advantage of the nuanced power variability provided by electric motors. The control glove can be operated one-handed, by touch alone, in any body position, yet the input transducer placement prevents accidental commands. An output transducer on the glove provides alerts on power-reserve (e.g. battery) status. The alerts are detectable either by touch alone or a quick glance with peripheral vision.

Disclosed are devices, systems, and methods, including an oxygen delivery device that includes an oxygen delivery module to produce at least concentrated oxygen, a gas moving device to deliver air to the oxygen delivery module, at least one motor to controllably drive the gas moving device, an energy source to power at least the at least one motor, a pressure sensor to determine a pressure level, and a purity sensor to determine oxygen purity value. The device also includes a controller to control, based on the oxygen purity value and the pressure level, at least the gas moving device's operations and the oxygen delivery module's operations to cause the pressure resulting from gas moving device to be substantially at a pre-determined pressure value and to cause the purity level of the oxygen produced by the oxygen delivery module to be substantially at a pre-determined purity value.
摘要:
A mobile telecommunications network includes a radio access network comprising base stations and one or more additional access points. An access point is connected to a network core by an IP transport broadband connection. The access point is configured to appear to the mobile terminal as a conventional base station—that is, for example, it communicates with the mobile terminal using GSM or UMTS transport protocols and does not require any modification to a standard GSM or UMTS mobile terminal. Access Points may not be under the direct control of the network provider, and so are more susceptible to security threats. The described system allows the network provider to verify that the access point through which a mobile terminal is about to communicate is a legitimate and trusted base station and/or is at a particular location. Differential charging may be performed in dependence upon a subscriber's location.

摘要:
A fire extinguishing and fire retarding method is provided comprising the step of confining a fire extinguishing and fire retarding agent in slurry, liquid or gaseous form within a shell wherein the shell comprises such an agent in solid form. An agent such as ice water, or liquid carbon dioxide is useful when employing the shell as “non-lethal” device. The solid shell is sublimable and will burst upon impact or upon exposure to the environmental conditions at the target site to release the contents of the shell as well as the fragments of the shell onto the target site.
