Title: Transition detection circuitry and method of detecting a transition of a signal occuring within a timing window
Inventor: SHIDHARTHA DAS
IPC: H03K3/037
Filed: 2015-04-28
Abstract: A transition detection circuit 20 (and method of operation) comprising a pulse generation circuit 25 to receive an input signal 10 and to generate a pulse signal PULSE in response to a transition in the input signal 10, and pulse detection circuitry 30 to assert an error signal ERROR on detection of the pulse signal generated by the pulse generation circuitry 25. The pulse generation circuitry has pulse control circuitry 35 to control a property of the pulse signal (such as pulse width) dependent on a timing window indication signal 40. In particular, when the pulse signal is generated at least partly whilst the timing window indication signal is set (see 415 figure 5B), the pulse control circuitry controls the property of the pulse signal (for example extends the pulse width) such that that generated pulse signal is detected by the pulse detection circuitry so as to produce an error signal (420 fig 5B). However when pulse signal is entirely generated whilst timing window indication signal is cleared (405 fig 5B), the pulse control circuitry controls the property of the pulse signal (narrow pulse width as in 405 fig 5B) such that the generated pulse signal is undetected by the pulse detection circuitry. Embodiments are provided in figures 4, 7, 9 and 10). In one embodiment, an inverse timing window clock signal CN controls the pull down current (315 figure 4 NMOS ) in a modified inverter pulse width control circuit (300 figure 4), whilst pull up PMOS devices (305, 310 fig 4) are gated via time delayed one-shot circuits (110, 105, and 135, 120, 125, 130 figure 4). The relative sizing of the PMOS/NMOS devices is important. The error signal is latched (latch 170, gated inverter 145, 330 figure 4) until reset by signal ERN->low. This approach gives rise to significant area and energy consumption savings, whilst still allowing reliable detection of timing errors.

Title: Systems and methods for processing images of objects
Inventor: JAMES IMBER
IPC: G06T15/50
Filed: 2015-10-27
Abstract: An image processing system and method for determining an intrinsic colour component of one or more objects for use in rendering the object(s) involves receiving one or more input images, each representing a view of the object(s), wherein values of each of the input image(s) are separable into intrinsic colour estimates and corresponding shading estimates together with a depth image represents depths of the object(s). Coarse intrinsic colour estimates are determined using the input image(s) and this coarse estimate is then bilaterally filtered using bilateral filtering guidance terms based on depth values derived from the depth image to generate the intrinsic colour component. The bilateral guidance terms may be further based on the colour and/or luminance values derived from the one or more input images. The depth values may also be derived by applying bilateral filtering to initial depth values from the depth image using guidance values based on luminance values derived from the one or more input images. The coarse intrinsic colour estimate may be derived using a global lighting estimate to determine a shading estimate together with surface normals derived from the depth image.

Title: Improving warm-up of a catalytic aftertreatment device
Inventor: GERALD BARR
IPC: F01N3/28
Filed: 2016-09-23
Abstract: An apparatus and method for improving warm-up of a catalytic aftertreatment device 20 in which flow to a catalyst brick 25 is controlled using a flow control device 30 to restrict exhaust gas flow to only a catalyst brick central when rapid heating is required to reach a light-off temperature and to otherwise allow the flow of exhaust gas to the entire front face of the brick. By restricting the area of the catalyst brick 25 to which exhaust gas can flow the energy density of the exhaust gas flowing to the central core is higher than it is when there is no restriction of flow thereby reducing the time required to warm-up the catalyst brick 25 to a minimum light-off temperature. The control device may comprise a ring of radially pivoting vanes 31 operated in unison by respective link arms 34 acted on by a common linkage 37 and electrically controllable actuator.

Inventor: S HARSHAL
IPC: G01N33/92
Filed: 2015-05-22
Abstract: An improved system and method for measuring the permeability of drugs/toxin chemical compounds utilizing phospholipid monolayer is disclosed. A phospholipid monolayer can be deposited on to a cellulose membrane by vertical lifting or Langmuir Schafer technique. The phospholipid monolayer or Langmuir Blodgett (LB) film can be coated on the cellulose membrane or porous support. Depositing the lipid onto porous support without the use of solvent and maintaining the lipid arrangement,packing similar to biological cell membrane is challenging. The lipid coated membrane support is attached to donor wells, which can be fabricated using Polystyrene tubes/ Poly acrylic tubes. The permeability of the drug/toxin/chemical compound can be further measured using the phospholipid monolayer by Boyden chamber approach. Such an improved method and system can be adapted for effective measurement of permeability of drugs/toxin chemical compounds through lipid layer in order to predict entry of such compounds into the blood stream. The current monolayer based system(LB- PAMPA) is solvent free, the lipid arrangement is similar to cell membrane and hence biomimetic, The system utilizes lipid monolayer which contains lipid molecules arranged in a definite order approaching packing in the cell membrane. The method can be adapted for mixture of lipids or pure lipids, the coating method is scalable and the entire system is High throughput and biomimetic.

Title: Vehicle remote park assist with occupant detection
Inventor: ERICK MICHAEL LAVOIE
IPC: G08G1/16
Filed: 2017-07-25
Abstract: Systems and methods are disclosed for vehicle remote park assist with occupant detection. An example disclosed vehicle includes range detection sensors (Fig.1, 104) and a remote parking unit. The range detection sensors determine whether a target parking space (Fig.1, 116) is narrow 406. The remote parking unit, in response to a request from a mobile device (Fig.1, 117) external to the vehicle, when the target parking space is narrow, scans, with occupant detection sensors (Fig,1, 108), the interior of the vehicle 418. Additionally, the remote parking unit, in response to detecting an occupant or passenger in the vehicle, sends a first notification to the mobile device 424. A narrow or tight parking space may be determined when a width of the space is less than a width of the vehicle with the doors open. If the target parking space is not narrow, the remote parking unit may determine likelihood that the space will become narrow 408 and scan the vehicle interior for an occupant. A warning may be produced if an occupant or person is detected in the vehicle.
