Patent GB-2541079-A (GB)
Title: Analog-to-digital converter
Inventor: JOHN PAUL LESSO
IPC: H03M3/04
Filed: 2013-06-26
Abstract: An analogue-to-digital converter for speech signals is operable in a low-power input monitoring mode to reduce standby power and is then placed in a high-resolution mode when input signals are detected so that speech recognition may be performed by a succeeding DSP (254, figure 9). A signal detector (252, figure 9) selects the high-resolution mode by enabling the feedback DAC 274 and the loop integrator amplifier 294, selecting the filter output Sfilt instead of the signal input Sin for input to the voltage controlled oscillator 300, and increasing the operating frequency of the VCO (figures 13 and 14). To further reduce power consumption the DSP is enabled only when input signals are detected, full speech recognition operation of the DSP being enabled only when a trigger phrase has been detected (figure 4).

Title: A Tactile switch for a mobile electronic device
Inventor: JOHN SPENCER BANDRINGA
IPC: H03K17/96
Filed: 2016-06-13
Abstract: A tactile switch on a mobile electronic device comprises a pressure sensitive interface 22 on an exterior portion of the device housing, and at least one pathway 34 coupled to and extending from the pressure sensitive interface to a switch mechanism 36 located remotely from the interface. The pathway may be formed in an interior portion of the housing and is filled by a viscous fluid which, when pressure is applied to the pressure sensitive interface, exerts pressure on the switch mechanism, causing the switch to make an electrical contact. The switch mechanism may be mechanical or a solid state sensor. The pressure sensitive interface may be shaped to conform to a contour of the housing. There may be plural pressure interfaces, each having a corresponding pathway and switch mechanism. A vibrator 39 or solenoid can transmit vibration to the housing or to the interface when the switch is actuated.

Inventor: ITAY KARIV
IPC: A61B6/12
Filed: 2010-09-24
Abstract: A tool dislodgement detection apparatus 10 includes and MPS 20 outputting position and orientation (P&O) readings for determining tool 26 motion. A control 12 generates an alarm based on the tool motion and dislodgement 2 criteria. The criteria includes whether the tool motion meets a condition based on the type of medical procedure or tool, the tool parking position, a patient characteristic (.e.g., age, weight, gender) or a physician preference. The criteria includes when the correlation between the tool motion and the cardiac, respiration and patient motion changes abruptly. In a prolapse detection apparatus, guidewire tip P&O readings determine a tip 68 motion vector 70. The control generates an alarm using the motion vector and predetermined criteria. The criteria include a substantial change in the tip orientation not accompanied by a corresponding position change and a change in the motion vector by about 180° accompanied by a corresponding position change no greater than a threshold.

Filed: 2017-09-29
Abstract: A request is received (200) for searching media (e.g. video or audio) data for a specific content (e.g. an object such as car, license plate, person, associated with a context such as weather, day/night, time), the data being obtained by at least one of a plurality of source devices configured to obtain media data. A subset comprising at least one device from the plurality is selected (230), each device being assigned a category based on the request and on an analysis of its obtained data (e.g. sampled), the selecting being based on the assigned category. The media data obtained by the at least one device of the selected subset is searched (240) for the specific content, thereby optimizing the search for samples. The most relevant sources (e.g. cameras) may therefore be searched, with those sources having little relevance to the object or context being avoided.

Title: System and method of creating entity records
Inventor: NIKHIL VINOD FULZELE
IPC: G06F16/35
Filed: 2018-03-27
Abstract: A method of creating entity records using a computer system comprises receiving 202 unstructured data from existing data sources, e.g. the internet. The unstructured data is then structured 204 to obtain data records comprising entity names and attributes, e.g. using a feature matrix. The data records are sorted 206 into buckets based on similar entity attributes. The buckets are grouped 208 into clusters using a pattern recognition algorithm, e.g. k-nearest neighbour algorithm. A prediction probability score, e.g. calculated with a random-forest classifier, is assigned 210 to each of the data records within the clusters. Data records are then combined 212 to form an entity record where the combined records comprise a prediction probability score higher than a predefined threshold. The method allows the automatic combination of data relating to the same person or entity into a single record, even in ambiguous situations, e.g. where two entities have the same name.

Title: Mechanical clutch
Inventor: NGAI KWONG WONG
IPC: F16D11/04
Filed: 2018-07-20
Abstract: The mechanical clutch includes a drive 20 and a driven 22 member for rotation around an axis of rotation, a clutch pin 31 engages with the drive and or driven member to mechanically and rotationally link the drive and driven member, and a clutch pin engagement surface 31. A corresponding engagement surface 28a is provided on the drive or driven members such that, when the engaged drive and driven members are rotated against a below threshold magnitude of rotational resistance the respective clutch engagement surfaces will co-act with one another to retain said rotational connection between the drive and driven member. When the drive and driven members are rotated against an above threshold magnitude of rotational resistance the respective clutch pin engagement surfaces engage each other to urge the clutch pins out of engagement. In use the clutch is part of a combination lock having a pressure plate 12 with a shoulder 42 which engages a shoulder 40 on the driven plate and is prevented from moving when the lock is locked, thus provides the threshold force to the driven plate. When the lock is unlocked the pressure plate can move when pushed by the driven plate, thus allowing the driven plate to rotate.
