Abstract: An integrated optical transducer for measuring displacement of a diaphragm comprises the diaphragm, a lens element and a substrate body having a waveguide structure and a coupling element. The diaphragm is arranged distant from the substrate body and substantially parallel to a main extension plane of the substrate body. The waveguide structure is configured to guide light from a light source to the coupling element and from the coupling element to a photodetector. The coupling element is configured to couple at least part of the light in the waveguide structure onto a light path between the coupling element and the diaphragm and to couple light reflected by a surface of the diaphragm from the light path into the waveguide structure. The lens element is arranged on the light path such that light on the light path passes through the lens element.

Abstract: Circuits, methods, and apparatus that can reduce clock induced current and voltage transients and emissions in lidar pixel arrays. A pixel array can include an array of pixels, where at any given time, different pixels in the pixel array perform different tasks and are clocked by clock signals having different phases or delays relative to each other. This temporal dispersion of tasks and clock signals can spread clock induced current and voltage transients and emissions throughout a clock cycle, thereby reducing their maximum amplitude.

Abstract: Techniques described herein provide memory redundancy. For example, the memory block for each pixel can be partitioned into multiple memory bins, and the number of memory bins can be larger than the number of time bins. Once a faulty memory cell is identified, an address associated with the memory bin that has the faulty memory cell can be skipped by an address generator. As such, the faulty memory cell is not used to store time-of-fight (ToF) information.

The bonding structures are arranged such that pressure ventilation openings are formed that connect the first cavity and the second cavity.

The bonded structure further comprises a plurality of connection elements physically connecting the first pads to the second pads. The surface of the integrated circuit component is tilted obliquely to the surface of the substrate component at a tilt angle that results from nominal variations of surface sizes of the first and second pads.

Abstract: An arrangement (2) to calibrate a capacitive sensor interface (1) includes a capacitive sensor (10) having a capacitance (cmem, cmemsp, cmemsm) and a charge storing circuit (20) having a changeable capacitance (cdum, cdump, cdumm). A test circuit (30) applies a test signal (vtst) to the capacitive sensor (10) and the charge storing circuit (20). An amplifier circuit (40) has a first input connection (E40a) coupled to the capacitive sensor (10) and a second input connection (E40b) coupled to the charge storing circuit (20). The amplifier circuit (40) provides an output signal (Vout) in dependence on a first input signal (?Verr1) applied to the first input connection (E40a) and a second input signal (?Verr2) applied to the second input connection (E40b). A control circuit (60) is configured to trim the capacitance (cdum, cdump, cdumm) of the charge storing circuit (20) such that the level of the output signal (Vout) tends to the level of zero.

Abstract: A MEMS sensor (1) comprises a MEMS transducer (10) being coupled to a MEMS interface circuit (20). The MEMS interface circuit (20) comprises a bias voltage generator (100), a differential amplifier (200), a capacitor (300) and a feedback control circuit (400). The bias voltage generator (100) generates a bias voltage (Vbias) for operating the MEMS transducer. The variable capacitor (300) is connected to one of the input nodes (I200a) of the differential amplifier (200). At least one of the output nodes (A200a, A200b) of the differential amplifier is coupled to a base terminal (T110) of an output filter (110) of the bias voltage generator (100). Any disturbing signal from the bias voltage generator (100) is a common-mode signal that is divided equally on the input nodes (I200a, I200b) of the differential amplifier (200) and is therefore rejected.

A second feedback path is coupled to the quantizer for providing a second feedback signal to the signal input being representative of the one or more higher significance bits.

Abstract: An HPLC module utilizes a combination of compound-dedicated hardware providing line clearance between differing radiosynthesis and includes multiple compound-dedicated HPLC inject valves, each inject valve directing a fluid to a serially-connected HPLC column and UV flowcell so as to prevent cross-contamination between differing radiopharmaceutical syntheses. The module provides a disposable fluid path from each UV flowcell allowing for radioactive detection, fraction collection, formulation and final product dispensing. In this manner, a level of GMP compliance is achieved that is suitable for meeting the requirements of an MHRA approved site-license.

Abstract: Methods and systems to facilitate the collaborative development, discovery and implementation of evidence-based, clinical pathways are disclosed. Clinicians, medical professionals or researchers, may use the Platform 105 in multiple implementation, such as integrated with a third-party system like an EHR 104 to build and find clinical pathways through a graphical interface, creating relational data records between steps in pathways. Further, users of the Platform 105 may be able to associate relevant content such as published evidence, supplemental content items (e.g., videos, images, documents, ICD, CPT, SNOMED codes, and external web pages), and other associated pathways which reside in the system's database. Users of the Platform 105 may be able organize themselves into groups and networks to develop single pathways collaboratively. Users may be able to find specific pathways in the Platform 105 through semantic search, querying for relationships which exist inside of individual pathways.

Abstract: A multi-stream optical interrogation flow cell (60) for a radiopharmaceutical includes a multiple flow cell body (10a-f) defining a first elongate fluid flowpath (A1-6;B1-6) therethrough for individually conducting a radiopharmaceutical therethrough in fluid isolation from other of the flow cell bodies. Each flow cell body further defines a first and second aligned UV transparent optical guides (36,38) and a first interrogation passageway (26a-f) extending between the first and second optical guides such that a portion of the elongate first fluid flowpath intersects the interrogation passageway such that the radiopharmaceutical flows in between the first and second optical guides. The first and second interrogation passageways of all of the flow cell bodies are optically aligned so that a single interrogation beam is able to extend through each of the interrogation passageways.
