Title: Biometric skin contact sensor and methods of operating a biometric skin contact sensor
Inventor: HENRICUS DERCKX
IPC: G06V40/13
Filed: 2020-09-29
Abstract: A capacitive biometric skin contact sensor comprising: an array of capacitive sensor pixels (Figs. 4-7); a current multiplexer 110 connected to the read-out channels of the pixel array (10,Fig.1); and an analogue to digital converter (ADC) 200 that provides a digital signal based on the read-out currents, wherein the sensor is configured to control at least one of the current multiplexer and the ADC (dashed lines) to switch between operation in a first and second sensing mode. The ADC comprises a dual slope integrator that can receive either an input from the multiplexor or a reference voltage Vref. A current mirror (amplifier) 120 may be provided and used in providing the first and second modes. The first sensing mode may indicate that skin is interacting with the sensing area and the second sensing mode the sensor obtains biometric data from the skin. The second sensing mode may provide higher sensitivity, higher resolution and sample time variation by: increasing charging time; increasing gain; controlling multiplexor operation; controlling ADC reference voltage and/or gate drive signals of the pixel array. The sensor may operate at a higher resolution and/or sensitivity in a first sub-region corresponding to skin contact.

Filed: 2020-09-02
Abstract: In an ice dispensing system (100), ice produced by ice producing machines (121, 122, 123, 124) is delivered to a user through an ice transferring subsystem (140). In the ice transferring subsystem (140), an ice container (142) is vertically moved to reach a selected machine for receiving ice therefrom. Advantageously, a vertical position of the ice container (142) is adjusted for adjusting an inner depth thereof allowable for storing ice such that a selected quantity of ice for delivery to the user is loaded into the ice container (142). The loaded ice container (142) is vertically moved to an ice dispensing channel (180) and unloads the ice thereto for dispensing to the user. In particular, the loaded ice container (142) is elevated to the ice dispensing channel (180) when the selected machine is positioned lower than the ice dispensing channel (180), thereby providing user convenience in procuring the ice from the ice dispensing channel (180) without installing the selected machine at a higher position than the ice dispensing channel (180) in utilizing gravity for ice delivery.

Filed: 2022-04-07
Abstract: A method for supporting cell reselection for a User Equipment, UE, operating in a non-connected RRC state (RRC-idle or RRC-Inactive) with one or more active data sessions is described. The UE sends a cell reselection request message to a serving cell base station. The serving cell base station sends a migration request message to a target cell base station and receives back a migration acknowledgement message including configuration information associated with the target cell base station for the one or more active data sessions. The serving cell base station sends the configuration information to the UE which is then configured for receiving data of the one or more active data sessions from the target cell. Alternatively, the UE sends a reselection request message to the target cell base station. The target cell base station retrieves a UE context from the old serving cell base station and sends configuration information to the UE. The active data sessions may include one or more Multicast Broadcast Service, MBS, sessions.

Title: Turbofan and air conditioner
Inventor: Ryutaro Asano
IPC: F04D29/30
Filed: 2020-11-25
Abstract: In this turbo fan, when the leading edge of each swept-back blade is positioned further forward in the rotational direction than the trailing edge, a junction between the leading edge and a main plate is set as a first point, and an intersection of the leading edge and a virtual plane perpendicular to a rotational axis and passing through an outermost circumferential section of a shroud is set as a second point, a first curve (L21) obtained by projecting the leading edge onto the rotational axis perpendicular plane has a first inflection point on the positive side in the rotational direction in a coordinate system where a virtual straight line that passes through the first point and the second point is an abscissa as seen from above in the axial direction of the rotational axis . The first curve has a convex portion that protrudes in the reverse rotational direction at a portion closer to the first point than the first inflection point, and a convex portion that protrudes in the rotational direction at a portion closer to the second point than the first inflection point. The trailing edge follows an arc centered on the rotational axis as seen from above in the rotational direction. A third curve obtained by projecting the trailing edge onto a cylindrical plane coaxial with the rotational axis protrudes in the rotational direction. A junction between the third curve and the shroud is located further rearward in the rotational direction than the junction between the third curve and the main plate. As a result, a reduction in suction efficiency and a deviation in the blade outlet speed distribution are suppressed.
