Title: Trigger frames adapted to packet-based policies in an 802.11 network
Inventor: Stéphane Baron
IPC: H04W74/06
Filed: 2015-07-10
Abstract: In 802.11ax networks with access points, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access points. To make more effective the usage of the network, the access point may design the trigger frame to force the nodes to send some categories of data. Resource units may be defined in trigger frames to be dedicated to small packets or to some access category data. Adjusting the time length of the resource units helps restricting the type of data that can be conveyed by the resource units. Also, using various frequency widths for resource units in the same trigger frame helps reducing padding in the resource units when various traffic types coexist.

Title: Active phased array antenna system with hierarchical modularized architecture
Inventor: HSI-TSENG CHOU
IPC: H04B7/08
Filed: 2016-12-20
Abstract: An active phased array antenna system 20 includes an array antenna 210 comprising a number of antenna units (N), a beamforming circuit 220 and a control unit 230 that provides phase control signals for beamforming. The beamforming circuit has a hierarchical structure based on phase shifters for receiving input signals (SI) and phase control signals (CS1-7) where the number of phase control signals (T) is smaller than the number of the antennas (T<N). For example, twelve (12) antennas are connected to a hierarchical phase shifter circuit having phase shifters 221, 222, 223. The shifters are placed in three hierarchies which respectively receive control signal groups: CS1-CS2, CSE3-CS4, CS5-CS7. In this way, 3 groups of respectively 2, 2 and 3 signals generate 12 phase signals (2*2*3=12) required by the antenna units for beamforming. The circuit structure may also include power divider/combiners 250 that interconnect the phase shifters. A further invention concerns a phased array antenna with a beamforming hierarchical circuit structure based on binary adders (figs 7&8).

Title: Inspection of components for imperfections
Inventor: JOHN MICHAEL NESBITT
IPC: G06T7/00
Filed: 2017-03-29
Abstract: An inspection method for optical components, such as lenses, prisms etc, that can be implemented to conform to performance specification MIL-PRF-13830 in order to grade surface imperfections, in particular scratches and digs. A dark-field microscope obtains a digital image of the component, and this digital image is processed to determine scratch and dig numbers. For scratches, the number is obtained by dividing the total intensity of the scratch by the scratch length. For digs, the number is obtained by determining dig diameter or by dividing the dig's total intensity by its area. According to our extensive testing, this automated digital image processing approach appears to faithfully mimic the subjective impression that a scratch makes on an expert inspector who is applying the visibility test of MI L-PRF-13830.

Title: Method of Separating Ions
Inventor: MARTIN RAYMOND GREEN
IPC: H01J49/26
Filed: 2017-05-17
Abstract: A method of separating ions according to their ion mobility comprises (i) accumulating a first population of ions in a first region 12 of an ion mobility separator 10; (ii) separating the first population of ions in the first region; and (iii) accumulating a second population of ions in the first region whilst the first population of ions are being separated e.g. in a second region 16 downstream. In other words, the first region may be switched from an ion mobility separation mode to a trapping mode to accumulate the second population of ions after the first population of ions has exited the first region but before they have exited the second region. The second population of ions may further be accumulated in an accumulation region 14 upstream of the first region during step (ii) and transferred into the first region during step (iii). The method may also be applied to a mass separation device.

Title: Current steering digital to analog converter
Inventor: FERGUS JOHN DOWNEY
IPC: H03M1/74
Filed: 2017-11-07
Abstract: Digital to analogue converter architectures are disclosed that enable transistors of binary-scaled size to be replaced by transistors of substantially the same size. This significantly reduces the size of the DAC on a wafer. According to the invention, a DAC comprises a plurality of FETs acting as current generators. The transconductance of the FETs is controlled by operating them at sub-threshold gate-source voltages. The size scaling of the FETs does not then need to follow the DAC current ratios. The disclosure provides for the control of transconductance by the inclusion of source resistors (fig.4). The resistors may be chained (figs. 5-7). Series transistors may be used to control the gate voltages (fig. 8-10). It is shown that a multiplicative effect on drain current can be obtained by linear steps in Vgs.
