Title: Sampling device
Inventor: Ulf Landergren
IPC: B01L3/00
Filed: 2020-08-10
Abstract: A device 100 for use in separating biological samples into solids and liquids has a front cover 1 and back cover 2, folded closed via hinge 11. A separation membrane 6 can act as a filter. Absorption membrane 7 can retain liquid. On opening the device, the separation and absorption membranes 6, 7 bend, thereby applying a compressive force to the membranes 6, 7. A free end 13 of the laminate 6, 7 may be attached to a straining portion 5, which is in turn attached to a fixation point 3 on the front cover 1. On opening the device, the straining portion 5 may slide under anchor 4 to compress the laminate 6, 7. A manual actuator, e.g. pull cord, may also bend the filter 6 and absorbing layer 7 (figure 12). The device may have optical identification means, e.g., a barcode. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Title: Tonearm Pivot
Inventor: RICHARD BRAINE
IPC: G11B3/14
Filed: 2020-08-18
Abstract: A tonearm 200a including an elongate member 8a, a suspension means 4a, 5a, a protrusion 1a and a contact surface 2a. The suspension means 4a, 5a suspends the elongate member 8a in an approximately horizontal position. The weight of the elongate member is substantially supported by the suspension means. The protrusion1a is arranged in opposing contact with the contact surface at a contact point 206a,such that action of a drag force substantially parallel to the length of the elongate member urges the contact surface 2a and the protrusion 1a into opposing contact, thereby producing a contact force which resists the drag force. By separating the means for supporting the weight of the elongate member and the means for resisting a drag force acting along the length of the elongate member, the drag force can be more effectively resisted thus providing a tonearm with improved properties.

IPC: G10L15/00
Filed: 2021-04-30
Abstract: Systems and methods for adaptive assessment may utilize test deliver policies derived from a multi-armed bandit approach in combination with an item response theory model. A monotonic policy may involve defining a difficulty range according to which test items are selected for delivery during an assessment, where the difficulty range is updated following delivery of each test item based on test-taker performance. A multi-stage policy may implement several stages for test item delivery, with a different initial difficulty range for test item selection being defined for each stage and the difficulty ranges being updated based on test-taker performance within each respective stage. A probability matching policy may involve defining an item difficulty probability distribution according to which test items are selected for delivery to a test taker, where the probability distribution is initialized based on test taker skill level and updated based on test taker performance.

Title: A method of configuring a string of pulses
Inventor: RICHARD DENNY
IPC: H01J49/00
Filed: 2022-11-18
Abstract: A method of configuring a string of pulses for an encoded frequent pulsing (EFP) acquisition, comprising generating a string containing N pulses, each pulse occurring at a respective time tn, the string of length T, wherein in use the string of pulses is repeated to create a stream of pulses. Respective span intervals tn(k) between each pulse ad every other pulse in the string are calculated, wherein k is the number of pulses in the span interval tn(k) (k being between 1 and N). The degree of overlap D of the calculated span intervals ∆tn are determined by calculating the relative difference ∂tn therebetween. The degree of uniformity S of the string of pulses and an objective function F = S – D for the string of pulses is calculated. The string is reconfigured to alter the time tn of at least one pulse in the string and the objective function F’ for the reconfigured string id calculated. If F’ is higher than F, the reconfigured string is adopted. This method is for demultiplexing mass data from a time of flight mass spectrometer.
