Title: Communication system
Inventor: VIVEK SHARMA
IPC: H04W76/04
Filed: 2016-02-29
Abstract: A communication system is disclosed in which a communication device establishes and engages in Voice over LTE (VoLTE) communication via a communication connection with a base station. The communication device obtains information indicating at least one criterion for determining whether VoLTE communication via the communication connection with the base station can be sustained. The communication device performs signal measurements for signals received from the base station and determines whether VoLTE communication via the communication connection with the base station can be sustained based on whether or not the signal measurements meet the at least one criterion. The signal measurement may take place before a VoLTE call is established. If a VoLTE call can not be sustained a communication may instead be set up in another Radio Access Network.

Title: A system and method for determining the age of an individual
Inventor: GARETH OWEN
IPC: G06V10/50
Filed: 2016-06-27
Abstract: The system consists of a pair of near infrared cameras (2, 3), a near-infrared light source (5), a visible light camera (4) and a controller (6) which may be a field-programmable gate array integrated circuit (FPGA IC). The system is configured to obtain multiple images; locate the face in the image; locate and use facial landmarks to map the face onto a template (9, Figure 3); segment the image into facial regions; compare pixels with their neighboring pixels to create a pixel distribution for each segmented image; combine all the distributions into one global histogram and perform linear regression on the histogram to determine an age value for the image. This is repeated for other images and an average age value calculated. The face recognition may be done with a Viola-Jones technique and the detected face image may undergo affine transformation (e.g. rotation, scaling, and translation) or may be cropped prior to being mapped onto the template. Locating of facial features may be done with a random forest decision tree and the pixel analysis may be a local binary pattern (LBP) technique. Age estimation is carried out with a known classification formula.

Title: Transmission method for trigger frame by a 802.11ax access-point
Inventor: PASCAL VIGER
IPC: H04W74/00
Filed: 2016-07-25
Abstract: An access point in a wireless communication network selects between contention 803 and preemption 802 transmission modes, then sends a trigger frame to the stations on the network using this mode, the trigger frame reserving for the stations a transmission opportunity on a communication channel including a plurality of resource units. The transmission mode may be selected 801 according to the nature of the trigger frame, its priority, or a measure of congestion in the network. The preemption mode may be implemented by the access point sending a trigger frame after PIFS (PCF interframe space) duration once the wireless medium becomes free. In a second aspect, the access point selects a transmission queue for the trigger frame, said queue associated with an access category which defines a priority for accessing the network. The trigger frame may then be transmitted according to the EDCA procedure, and may solicit the transmission of uplink multi-user OFDMA.

The differential outputs may be supplied to a differential analogue to digital converter. A processor, or computer program, may be configured to trigger a measurement state of the apparatus when unwanted motion disturbances are below a threshold level and maintain a motion recognition state when they are not. The apparatus is suitable for use with seismocardiographic signals which are typically noisy and have a desired signal with relatively low amplitude.

Title: Low-temperature polycrystalline silicon semiconductor thin-film transistor-based goa circuit
Inventor: JUNCHENG XIAO
IPC: H03K17/687
Filed: 2015-02-06
Abstract: A low-temperature polycrystalline silicon semiconductor thin-film transistor-based GOA circuit comprising multiple cascade GOA units. A level N GOA unit comprises a pull-up control part (100), a pull-up part (200), a first pull-down part (400), and a pull-down holding circuit part (500). The pull-down holding circuit part (500) employs a high-low potential backstepping design and is provided with lowered first, second, and third direct current constant voltage potentials (VSS1, VSS2, and VSS3) and a direct current constant voltage high potential (H). This solves an impact on a GOA driver circuit by properties of the low temperature polysilicon semiconductor thin-film transistor itself, particularly a GOA functional shortcoming brought forth by the problem of electric leakage, also solves the problem that the potential of a second node in the pull-down holding circuit part in an existing low-temperature polycrystalline silicon semiconductor thin-film transistor-based GOA circuit cannot remain at an increased potential during inactivity, and effectively maintains a low potential for a first node (Q(N)) and an output end (G(N)).

Title: Methods and devices associated with direct communications in a radio access network
Inventor: ROY RON
IPC: H04W88/04
Filed: 2017-05-05
Abstract: A wireless communication device 502 operates in a radio access network as a network relay device (for instance a UE-to-Network relay) to a remote device 500. A short range communication channel is used between the network relay device and remote device. The wireless communication device receives a control indication signal 506 from the remote device as an indication of future data 512 between the communication device and the remote device via the short range communication channel, forming part of a sidelink communication between the relay device and the remote device. The relay device decodes the control indication signal from the remote device to extract a time allocation for future data. The network relay device may signal a base station (e.g. eNB) with an uplink grant request for the future data. The future data requirements may be combined in a PSCCH message and include at least one of an expected decode time, possible data size and logical channel group to which the data belongs. The uplink grant request may comprise a Predictive Request for UL Grant (PRG) message. A Buffer Status Report (BSR) message may include the PRG. The relaying of data may take place in a FeD2D environment.
