Abstract: A system for non-invasive hematological measurements includes a platform to receive a body portion of a user and an imaging device to acquire a set of images of a capillary bed in the body portion. For each image, a controller detects one or more capillaries in the body portion of the finger to identify a first set of capillaries by estimating one or more attributes of each capillary (e.g., structural attributes, flow attributes, imaging attributes, or combinations thereof), wherein at least one attribute of each capillary meets a predetermined criterion. The controller also identifies a second set of capillaries from the first set of capillaries such that each capillary of the second set of capillaries is visible in a predetermined number of images of the set of images.

Abstract: Aspects of the invention include systems and methods configured for federated automatic machine learning. A non-limiting example computer-implemented method includes defining a search process including a model configuration for building an automatic machine learning pipeline definition and distributing the search process across a plurality of parties. Each member of the plurality of parties retains federated data including training data and holdout data. The method includes receiving, from each member of the plurality of parties, an evaluation result of the model configuration against respective holdout data and aggregating the received evaluation results to define aggregated parameters. A new pipeline definition is generated from the aggregated parameters and trained local models received from each member of the plurality of parties are aggregated to define an aggregated model. Each trained local model includes the new pipeline definition.

Abstract: Monitoring resource allocation requests to computer resources shared between a plurality of computers includes detecting an allocation request by an application for a first set of the plurality of computer resources and assigning the application to a group, wherein each member of the group comprises a respective application having an associated allocation request for an associated set of the plurality of computer resources. Determining that the first set of the plurality of computer resources cannot be allocated by the application, and determining that the first application generates a function call instructing other members of the group, if any, to request allocation of their associated set of the plurality of computer resources results in incrementing a counter value corresponding to the group. A message is sent when the counter value exceeds a predetermined threshold.

Abstract: Managing computer resource allocation includes detecting, by one computer amongst a plurality of computers, generation of an allocation request, wherein the allocation request requests exclusive access, by the one computer, to a computer resource shared between the plurality of computers; determining a period of time that has elapsed since detection of the generation of the allocation request; determining that a delay has occurred when the period of time has exceeded a predetermined threshold; and then, transmitting, by the one computer, a delay message based on the delay to each of the plurality of computers.

Abstract: A regional anesthesia catheter used with a guide such as for example a needle cannula has a distal portion integrally connected to a main portion of the catheter by a junction portion that has a cross-sectional profile different from the distal and main portions, so as to predispose the distal portion of the catheter to move in a given direction when the distal portion is not guided by or constrained by the needle cannula. The cross-sectional profile of the junction portion may be configured in a particular shape, or be constructed to have a flexibility that predisposes the distal portion to bend, curve or move toward a given direction.

A number of portions of a catheter may be configured to bend at a predefined direction. Further, a catheter may be configured to have a cross sectional profile or a predefined flexibility along its entire length to cause the catheter to move in a predefined direction.

Abstract: A demountable barrier (8) for substantially preventing access of water into premises (2) through an access region (4) provided in a wall (6) of the premises. A frame member (10) has a longitudinal channel (20) in a first face (22) open towards the wall of the premises. A resilient membrane (30) is secured to the frame member and framed by the frame member and overlying and closing the longitudinal channel. A non-return air valve (28) extends to the longitudinal channel from a second face (24) of the frame member and is sealed through an aperture provided in the frame member. A compressible sealing member (38) is located between the frame member and the wall of the premises and pump means (40) provides pressurised air into the longitudinal channel through the non-return air valve, to effect ballooning of the resilient membrane overlying the longitudinal channel and compression of the compressible sealing member, whereby a substantially water-tight seal is effected between the frame member and the wall.

Abstract: The present invention provides a means to implement amplitude and phase modulation digitally and directly at an RF frequency that benefits from high output power without the use of amplifiers. This is accomplished by the combination of two varying amplitude and phase vectors. A reference oscillator produces a carrier signal, which is supplied to two digital delay lines composed of a sequence of delay banks. The delay lines are controlled by lookup tables that are updated by the vector control circuit, used to determine the delay of each digital delay line. The output of each delay line is multiplexed to a switching bank which is also controlled by the vector control circuit. The output of the switching bank, in combination with a summer, is used to produce discrete amplitude adjustment of the vector.

Abstract: The present invention provides a means to implement amplitude and phase modulation digitally and directly at an RF frequency that benefits from high output power using non-linear amplifiers. This is accomplished by the combination of two constant amplitude phase varying vectors. A reference oscillator produces a carrier signal, which is supplied to two digital delay lines composed of a sequence of delay banks. The delay lines are controlled by lookup tables that are updated by the vector control circuit used to determine the delay of each digital delay line. The delay of the lines are set in such a way as to produce two vectors with the desired phase shift that, when summed together, produce a vector with the desired phase and amplitude characteristics.
