|20140104695||SHAPED GRADIENT LENS - One embodiment provides a method for receiving parallel rays at a lens. A first surface of the lens can receive first substantially parallel rays incoming from a first direction. The first surface of the lens also can receive second substantially parallel rays incoming from a second direction that is substantially different than the first direction. The lens can focus the first substantially parallel rays onto a first focal point on a second surface of the lens and focus the second substantially parallel rays onto a second focal point on the second surface of the lens, the second focal point being different than the first focal point.||04-17-2014|
|20140086348||METHOD AND SYSTEM FOR COMMUNICATING INFORMATION IN A DIGITAL SIGNAL - The present invention relates to a communication method, system and signal, and in particular to a method and system for communicating information in a digital signal. It has particular application to satellite or terrestrial packet-based multi-user radio communication systems. A method for communicating information in a digital signal comprising data symbols is disclosed, wherein the information is encoded in a sequence characteristic of pilot symbols distributed amongst the data symbols, such that a receiver is able to determine the sequence characteristic and retrieve the transmitted information. The invention allows information to be encoded into a sequence characteristic of pilot symbols, rather than relying on modulating such information onto the pilot symbols themselves. This allows a significantly larger number of pieces of information to be transmitted than hitherto possible, and the technique is more resistant to large frequency errors than prior techniques.||03-27-2014|
|20130100536||SHAPED GRADIENT LENS - One embodiment provides for a gradient lens having a first substantially hemispherical member comprising a first convex surface and a base and a second substantially hemispherical member projecting away from the base of the first hemispherical member and comprising a second convex surface. The gradient lens also includes a plurality of gradient layers disposed within the first hemispherical member, each gradient layer concentrically aligned to the first hemispherical member and comprising an index of refraction different than that of adjacent gradient layers.||04-25-2013|
|20120173038||Vehicle Mount Computer with Configurable Ignition Switch Behavior - A vehicle mount computer having a configurable behavior controlled by a vehicle's ignition switch. A user can configure the computer to perform an action, switch modes, or execute a software application in response to the ignition switch being pressed or the position of the ignition switch being adjusted. For example, the computer can be configured to switch to a standby mode or hibernation mode, shutdown, prompt the user to select an action, or do nothing in response to the ignition switch being placed in an off position. The ignition switch can be electrically coupled to an input of the computer so that the computer's operating system or another application can monitor the status of the ignition switch. The operating system or application can cause the computer to perform the configured response upon detecting a change in the ignition switch's position or an actuation of the ignition switch.||07-05-2012|
|20120170203||Quick Mount System for Computer Terminal - A mounting system for quickly attaching and detaching a computer terminal from a mounting station. The mounting station can be semi-permanently attached to an object, such as on forklift or a non-mobile structure, such as a wall. The mounting station can include a power input port for receiving external power for the computer terminal and one or more communication ports for providing data communication between the computer terminal and another device. The computer terminal includes an electrical connector that engages an electrical connector of the mounting station to receive the supply power and facilitate the data communication between the computer terminal and other device. The computer terminal and/or the mounting station can include a locking mechanism that releasably couples the computer terminal to the mounting station such that the electrical connectors maintain proper contact.||07-05-2012|
|20120169614||Computer Terminal with User Replaceable Front Panel - A computer terminal with a removable front panel having one or more user interfaces, such as a touch sensitive display and a keypad or keyboard. The front panel can be removably attached to the computer terminal, for example using a multitude of screws or other mechanical fasteners. The computer terminal can include an electrical connector that engages an electrical connector of the front panel to facilitate signal flow between components of the front panel and components of the computer terminal. Supply power also can be provided to components of the front panel via the electrical connectors. The removable front panel can be replaced in a quick and simple manner, for example when a user interface is damaged or rendered inoperable.||07-05-2012|
|20110193649||INTEGRATED CIRCULATORS SHARING A CONTINUOUS CIRCUIT - The present invention is directed to a circuit assembly that includes an integrated circulator assembly. The circuit assembly has a first substrate, which contains a continuous circuit trace that includes a circulator component from the circulator assembly and at least one electrical component from the circuit assembly. A second substrate is disposed beneath the first substrate and includes a cladding on one surface. The second substrate contains an aperture that accepts a ferrite element, which is axially aligned with the circulator component of the circuit trace. A conductive material is placed across the ferrite element so that it forms a continuous ground plane with the cladding, which is common to the entire circuit trace. The circulator assembly also contains a magnet bonded to the ferrite element. The circulator assembly may also include a yoke disposed below the magnet to shield the circulator from external magnetic fields.||08-11-2011|
|20090108953||MULTI-JUNCTION WAVEGUIDE CIRCULATOR WITH OVERLAPPING QUARTER-WAVE TRANSFORMERS - An improved multi-junction waveguide circulator overlaps two quarter-wave dielectric transformer sections so that the transitional sections occur concurrently in the same length of waveguide. Consequently, the two quarter-wavelength sections require a total length of between one-quarter wavelength and one-half wavelength, with no air gap between the two sections along the length of the internal cavity. The improved waveguide circulator can be implemented in variations from a minimum of two ferrite circulator elements held in close proximity to one another to any number of ferrite elements as required to achieve the desired isolation performance or to create a switch matrix with any combination of input and output ports. The improved waveguide circulator minimizes the length of the transitions between adjacent ferrite elements and thus reduces losses, component size, and mass.||04-30-2009|
