Abstract: Systems, methods, and machine-readable instructions stored on machine-readable media are disclosed for adjusting a time limit for a test based on one or more indications of availability. A test is executed, wherein the test includes a time limit. A determination is made that the time limit is exceeded. In response, the time limit is adjusted based on one or more indications of availability.

Abstract: A method includes, receiving a first version of a software patch for an application. The method further includes receiving a second version of the software patch, the second version being associated with an upstream version of the application. The method further includes, comparing the first version of the software patch with the second version of the software patch, the comparing accounting for differences between the first version of the software patch and the second version of the software patch that result from differences between the application and the upstream version of the application. The method further includes, in response to comparing, tagging the first version of the software patch as a match when there are no differences other than the differences between the first version of the software patch and the second version of the software patch that result from differences between the application and the upstream version of the application.

Abstract: A particle characterisation apparatus comprising: a light source for illuminating a sample with a light beam; a detector arranged to detect scattered light from the interaction of the light beam with the sample; a focus tuneable lens arranged to collect the scattered light for the detector from a scattering volume and/or to direct the light beam into the sample, a sample holder with an opposed pair of electrodes and configured to hold a sample in position in a measurement volume between the pair of electrodes such that a planar surface of the sample is aligned orthogonally to the electrode surfaces, the planar surface adjacent to the scattering volume, wherein adjustment of the focus tuneable lens results in adjustment of the relative position of the planar surface and the scattering volume by moving the scattering volume.

Abstract: A solid state light shadow clock including construction of multiple light sources about the perimeter illuminated inward to cast shadows displaying apparent rotation about the center at the speed of clock hands; at a speed of one revolution per hour, at the speed of one revolution per twelve hours, and at the speed of one revolution per minute; a circumferential inward facing arrangement of light emitting devices to cast shadows at various lengths and color combinations. The clock comprises radial shadows cast in representation of the arms of a clock. The shadow clock display may be incorporated in devices ranging in size from portable devices to large public displays.

Abstract: A coherent laser radar (lidar) device is described. The device has a transmitter portion that comprises a single wavelength laser source, a conversion means (such as an electro-optic modulator) for producing a combined light beam that comprises at least two component light beams of discrete wavelength from the output of said single wavelength laser source, and transmit optics to direct the combined light beam to a remote target. Each component light beam of the combined light beam traverses the same optical path from the single wavelength laser source to the transmit optics. The device is used to make differential absorption measurements.

Abstract: Lenses for lamps can improve the quality of the light emitted through lens by interacting with the light bulb. Photoluminescent dyes as well as non-photoluminescent dyes may be incorporated into a polycarbonate lens in order to shift the chromaticity of the light source. Further, design features such as grooves or protrusions may be incorporated into the lens to allow light produced by the photoluminescent material to escape the lens and be added to the emitted beam to further shift the chromaticity. The emitted beam is of a legal color and intensity as defined per the SAE J578 and SAE J1383 standards. The lighting performance may also be improved in such manner as reducing discomfort glare, increasing brightness or producing a beam that enhances road visibility at night to the human eye.

Abstract: A coherent differential absorption lidar (DIAL) device 2 comprises a transmit portion 4 for directing a combined light beam to a remote target and a receive portion 5 for receiving light returned from the remote target and for coherently mixing the received light with its associated local oscillator beam. The combined beam comprises at least two component light beams of discrete wavelengths. The device further comprises a signal correction means. The signal correction means comprising a means for extracting a portion of each component light beam from the transmit portion, a means for introducing a frequency difference 62 between each extracted component light beam and its associated local oscillator beam and a means for directing the extracted beam into the receive portion. This provides an additional correction signal thereby improving device performance.

Abstract: A throttle body assembly (10) including a throttle plate (22) mounted in the main bore (16) of the throttle body. Either the throttle plate, the bore or both are pre-sludged around the throttle plate/bore interface, using a sealant (24) that is cured with Ultraviolet energy, in order to maintain better air flow control over the life of the throttle body.

Abstract: A magnetic sensor including a coil for sensing a changing magnetic field developed by paper currency moving past the magnetic sensor. A capacitor forms a tuned circuit with the magnetic sensor coil to pass only those signals lying within a predetermined frequency range. A comparator compares the signals lying within the pass band with a predetermined threshold to determine the presence or absence of genuine currency. The tuned circuit significantly improves the signal to noise ratio of the sensing means and hence, significantly improves the ability to determine the genuineness of the currency. In a second embodiment, the presence of a magnetic field having a field strength above the predetermined threshold is utilized to pass timing pulses for clocking a counter. A decoder gate coupled to the counter indicates the presence of a genuine bill, only after a predetermined count has been reached.
