A case for a portable electronic device (especially for an iPhone and the like) comprises a shell 50, an electroluminescent (EL) panel 10 and associated power and control electronics housed on a printed circuit board 20. The electronics on the PCB include a connector 22 for mating with a corresponding connector on the portable electronic device so as to form an electrical connection to a power source in the portable electronic device. Another of the electrical components is There are further provided an inverter 24 and a transformer 26 to convert the low voltage DC power from the portable electronic device into approximately 180 V AC as required to power the EL panel 10. The shell 50 has a clear back 52 through which light produced by the EL panel 10 shines. Interchangeable graphics panels 100 can be slid into a pocket disposed between the EL panel 10 and the back 52 of the shell so as to customise the visual appearance of the case and hence the portable electronic device inside.

Solid-state lasers pumped by incoherent or partially coherent, monochromatic light sources such as high power VCSEL arrays. Efficient and uniform injection of pumping energy into gain medium is achieved through spectral match of the pump source with the gain medium absorption and multi-bounce reflections of unabsorbed pump light in a diffusing pump chamber. One preferred embodiment of the diffusing pump chamber is a hollow cylinder coaxially surrounding the gain medium. One or more transparent windows, slit-shaped or otherwise, for transmission of pump light are evenly distributed around the perimeter of the chamber and are parallel to the axis. Another preferred embodiment of the diffusing pump chamber is a highly reflecting compound parabolic concentrator. A 2-D VCSEL array is employed as the pump source and the gain medium is located at the focusing point of the chamber. This invention demonstrates solid-state lasers that are compact, robust, low-cost, and able to produce high power output in CW or pulse modes for practical applications. An important application of the present invention is high-power solid-state lasers featuring wavelength conversion such as optical parametric oscillation and second-harmonic generation. Another important application of the present invention is injection seeding, especially for pulse mode with high repetition rates.

Method and apparatus for high field asymmetric waveform ion mobility spectrometry in an electronic chip assembly, including an input section, an ion filter and detection section and a control section, in which ion filtering proceeds in a planar chamber under influence of high field asymmetric periodic signals, with detection integrated into the flow path, for producing accurate, real-time, data for identification of a broad range of chemical compounds.

A spectrometer employs multiple filters having complex filter spectra that can be generated robustly from received light over short optical path lengths. The complex filter spectra provide data that can be converted to a spectrum of the received light using compressed sensing techniques. The result is a more compact, easily manufactured spectrometer.

A drop-in adjustable trigger assembly has a camming safety linkage to selectively move and engage a bolt sear to positively prevent movement of the bolt sear. The drop-in trigger assembly housing carries a pivoting bolt sear engagement member which is connected to a sear safety linkage. The housing has a sear safety linkage slot defined therein which guides the pivoting sear safety linkage in response to actuation of an upwardly projecting thumb safety lever's actuation. A trigger bracket preferably carries a removable, reversible trigger shoe and is configured to pivot within the housing about a pivot point within the housing, and the trigger bracket carries an adjustable rocker having (preferably) a first stage movement adjustment and a second stage length adjustment. The pivoting safety mechanism's safety linkage pivots rearwardly to push upon or cam the bolt sear upwardly, thus disengaging the bolt sear from the trigger sear.

A gas-separation membrane assembly, and a gas-separation process using the assembly. The assembly incorporates multiple gas-separation membranes in an array within a single vessel or housing, and is equipped with two permeate ports, enabling permeate gas to be withdrawn from both ends of the membrane module permeate pipes.

Solid-state laser(s) pumped by incoherent, monochromatic light from sources such as LED arrays and integrating technologies such as high power LED arrays and solid-state laser materials in conjunction with efficient and uniform absorption of pumping energies through a diffusing pump chamber. The resulting laser(s) are compact, robust, low-cost, and able to produce high power output for practical applications. It may efficiently operate over wide temperature and performance ranges, at CW or pulse modes, even with ultra short pulse width and / or extremely high repetition rates. Our inventive structure(s) is / are highly flexible and applicable to a large group of lasing media including those with very short upper state life times. Advantageously, they may be applied to a plethora of laser systems at wavelengths that have important applications and unavailable to other direct pumping technologies.

The apparatus and methods of the present invention provide quiet, compact, robust hardware that can accurately produce a wide range of tactile frequencies at a perceptually constant intensity. For greater expressiveness, some apparatus for moving the skin in multiple axes are also disclosed. Signal processing methods are presented to enhance the user's experience of audio spatialization. The methods transform audio signals into directional tactile cues matched to the time resolution of the skin, and which exploit directional tactile illusions.

A remote operated vehicle system comprises a topside, a fish equipped with a GPS receiver, a transmitter for transmitting GPS position data, and a receiver operable to receive the transmitted position data. Transmission may be from the fish to the topside or from the topside to the fish. Alternatively, a second transmitter and receiver give two-way transmission. These arrangements allow the position of the fish to be monitored or tracked, so that it can be readily rescued in the event of damage or breakdown. Alternatively, predetermined position data can be sent to the fish, allowing it to automatically navigate a desired route. Particular embodiments include an umbilical cable for connecting the fish and the topside together and operable to carry signals, including position data, between the two, an additional GPS receiver on the topside so that the fish can navigate to the topside unaided, and a buoyancy control device which brings the fish to the surface.

The present invention provides for a digital holographic microscope using a holographic interferometer and incorporating a TIR sample mount and microscopic imaging optics. The microscope uses phase shifting from frustrated internal reflection within a prism to measure nanometric distances. The invention also provides for a numerical reconstruction algorithm of an inclined surface of the object / prism.
