Title: A self-powered portable barrier system with overheight sensor for controlling traffic
Inventor: NEIL SAMPSON
IPC: G08G1/04
Filed: 2019-08-05
Abstract: A self-powered portable barrier 5 is located adjacent a road 4 on a worksite with an overhead hazard. The barrier has a gate 7 driven by a motor to either one of a closed position obstructing passage along a road 4 and an open position allowing unobstructed passage. A controller in the barrier controls operation of the motor in response to communications from a communications system. A ground engaging support 9 is deployed spaced up or down the road so that a sensor 8 attached to the ground engaging support can be deployed at a height corresponding to safe passage under the overhead hazard and projecting a beam 12 across the road. If an over height vehicle E approaches the barrier it is detected by the sensor which transits a signal to the barrier 5. The controller responds by moving the gate 7 to the road closed position obstructing the passage of the vehicle until the over height condition is resolved.

Title: Contrast-based autofocus
Inventor: Nerhun Yildiz
IPC: H04N5/232
Filed: 2019-09-10
Abstract: Contrast-based autofocus in a camera, comprising: obtaining image pixel data from the camera sensor 118; dynamically/automatically selecting a subset of the image pixel data 120; processing the selected subset of image pixel data to generate contrast data 122; and processing the contrast data to determine a focus setting for the camera 124. Preferably, the subset is selected based on reliability estimates such as noise, or dynamic range (where noisy or low dynamic range regions are avoided). The subset selected may comprise only the pixels of a given colour from a colour filtered image sensor array (before demosaicing), for example, by setting certain pixels to zero. The contrast-based autofocus method may use a bandpass filtering process, the bandpass filtering process comprising: using an autoregressive (aka infinite impulse response, IIR) filter; and using a finite impulse (FIR) filter. Other disclosed inventions relate to setting focus based on processing (e.g. by a weighted sum) determined settings (which could be normalised) for two different regions or images; or converting input image data from a sensor to floating point format for storage, and converting retrieved stored data back to fixed point format for processing.

Title: Customizable microfluidic device with programmable microfluidic nodes
Inventor: EMMANUEL DELAMARCHE
IPC: F16K99/00
Filed: 2018-06-20
Abstract: The invention is directed to a microfluidic device. The device includes an input microchannel, a set of m distribution microchannels, a set of m microfluidic modules and a set of m nodes. The m microfluidic modules (m ≥ 2) are in fluidic communication with the m distribution microchannels, respectively. The one or more nodes of the set of m nodes branch from the input microchannel, and further branch to a respective one of the set of m distribution microchannels. In addition, a subset, but not all, of the nodes are altered. The nodes of the set of m nodes have different liquid pinning strengths. As a result, the extent in which a liquid passes through one or more of the m microfluidic modules varies based on the different liquid pinning strengths, in operation. Additional sets of nodes may be provided to allow liquid to pass through ordered pairs of modules.

Title: Missile
Inventor: RICHARD WILLIAM CRONK
IPC: H05K7/20
Filed: 2020-04-09
Abstract: A missile comprises a thermal link between an electronics unit 230 and an outer skin 210. The thermal link comprises a jumping-drop vapour chamber 240-260 arranged such that, when the outer skin is at an elevated temperature relative to the electronics unit, the electronics unit is thermally insulated from the outer skin; and such that, when the outer skin is at a lower temperature relative to the electronics unit, the electronics unit is thermally linked to the outer skin. The thermal link may comprise a hydrophilic evaporating surface in thermal communication with the electronics unit and a hydrophobic condensing surface in thermal communication with the outer skin. When the skin is relatively cool water vapour may condense on the hydrophobic surface and jump to and be absorbed by the hydrophilic surface once condensed droplets become large enough, to then evaporate to cool the electronics. When the skin is relatively hot no condensation can occur resulting in an insulating effect. To further prevent the electronics from overheating when the skin is relatively hot, a phase-change material 270 may be associated with the electronics.

Title: ASAFEAS- A Self-Activating Fire Extinguisher and Alarm System for appliances
Inventor: OLIVER STEPHEN WADE
IPC: A62C37/08
Filed: 2020-09-30
Abstract: An apparatus which automatically responds upon detection of a fire within an electrical apparatus comprising a main reinforced body 1.4 which attaches to an appliance via slider or other fixing 2.2 and further comprises a frangible cover 2.1. Wired around the frangible cover are a primary fuse(s) 1.3 and a further secondary fuse(s) 2.4 deploy at a different rate to ignite the detonator that creates an alarm noise within the capsule and rupture the frangible cover and expel the fire suppression agent in the direction of the appliance’s electronics, without spreading shrapnel. The capsules reinforcement(s) absorb the shockwave and sound wave, to prevent damage to the appliance from the detonator and reduce the noise of the alarm to not cause any concussive damage. The fuses from each capsule can be wired together and connected allowing a circuit of capsules to be installed in/on an appliance to minimise spillage of fire suppression agents, such as sodium carbonate.

Alternatively, an amplifying device (Fig.1, 200) for amplifying a signal from a radiation sensor includes a signal amplifier and an output unit; the signal amplifier comprises first and second amplifiers for amplifying an input signal and an offset signal, respectively. The output unit generates a digital output signal indicating a difference between the amplified input and offset signals. Additionally, a radiation detection apparatus (Fig.1, 1) includes a radiation detection unit, the amplifying device (Fig.1, 200), and a communication unit to transmit the digital output signal to an external device. The amplifying device may be used to compensate for a change in amplifier characteristics due to radiation.

Title: Enhanced low precision binary floating-point formatting
Inventor: SILVIA MELITTA MUELLER
IPC: G06F7/499
Filed: 2019-05-30
Abstract: Techniques for operating on and calculating binary floating-point numbers using an enhanced floating-point number format are presented. The enhanced format can comprise a single sign bit, six bits for the exponent, and nine bits for the fraction. Using six bits for the exponent can provide an enhanced exponent range that facilitates desirably fast convergence of computing-intensive algorithms and low error rates for computing-intensive applications. The enhanced format can employ a specified definition for the lowest binade that enables the lowest binade to be used for zero and normal numbers; and a specified definition for the highest binade that enables it to be structured to have one data point used for a merged Not-a-Number (NaN)/infinity symbol and remaining data points used for finite numbers. The signs of zero and merged NaN/infinity can be "don't care" terms. The enhanced format employs only one rounding mode, which is for rounding toward nearest up.
