Abstract: Provided herein is a digital care circle platform for electronic communication between a senior and virtual care circle members. The digital care circle platform may include a chatbot and an application associated with the senior, a mobile application associated with the plurality of virtual care circle members, at least one processor in communication with at least one memory device, and one or more servers, sensors, wearables, and transceivers. The at least one processor may be configured to: (i) accept event posts from the senior via the chatbot and application and from each virtual care circle member of the plurality of virtual care circle members via the mobile application, (ii) detect pro-active check-ins from the senior, and (iii) generate, once a pro-active check-in is detected, an electronic communication detailing the pro-active check-in as a pro-active check-in event, and transmit the pro-active check-in event to the virtual care circle members.

Abstract: Provided herein is an engagement and care support platform (“ECSP”) computer system including at least one processor in communication with at least one memory device for facilitating senior user engagement. The processor is programmed to: (i) register a user through an application, (ii) register a caregiver associated with the user through the application, (iii) generate a senior profile based upon user personal and scheduling data, (iv) build a daily interactive user interface that reflects the senior profile, (v) display the daily interactive user interface at a first client device associated with the user, (vi) cause the first client device to initiate a daily interaction prompt to the user, (vii) determine whether any user interaction was received in response to the daily interaction prompt, and (viii) transmit a daily update message to a second client device associated with the caregiver, including an indication of whether any user interaction was received.

Abstract: An example material testing apparatus includes: guide means; sample holding means for holding a sample; force means for applying force to the sample; a crosshead arranged to support at least a portion of one or both of the sample holding means and the force means, wherein the crosshead is moveable about the guide means; automated clamping means configured to apply a releasable clamping force between the guide means and the crosshead to secure the crosshead at a location with respect to the guide means, and a controller configured to control the automated clamping means to apply the clamping force between the guide means and the crosshead.

Abstract: A calibration sheet is located at a first position where its surface substantially corresponds to the expected position of a patient surface lying on a mechanical couch during treatment. Images of the calibration sheet are obtained and processed to ascertain relative locations and orientations of the image detectors obtaining the images and optical distortion parameters indicative of optical distortions present in the obtained images of the calibration sheet. The calibration sheet is then re-located to a known position relative to the iso-centre of the treatment apparatus and images of the re-located calibration sheet are obtained and processed to determine a transform corresponding to the relocation of the calibration sheet from the first position to the iso-centre of the treatment apparatus. Data indicative of optical distortions present in the images and data indicative of the locations and orientations of the image detectors relative to the iso-centre of the treatment apparatus are stored.

Abstract: Some embodiments are directed to a target surface including one or more three-dimensional projections, each projection including a multiplicity of planar side surfaces, a stereoscopic camera operable to obtain images of the target surface, and a processing module operable to process images obtained by the stereoscopic camera of the target surface together with data identifying the position and orientation of the stereoscopic camera relative to a defined point in space to determine the positions relative to the defined point in space of the planar side surfaces defined by the at least one or more three-dimensional projections.

Abstract: A calibration sheet (100) is located (S4-1) at a first position where its surface substantially corresponds to the expected position of a surface a patient (20) lying on a mechanical couch (18) during treatment. Images of the calibration sheet (100) are obtained and processed (S-4-2, S4-3) to ascertain the relative locations and orientations of the image detectors obtaining the images and optical distortion parameters indicative of optical distortions present in the obtained images of the calibration sheet (100). The calibration sheet (100) is then re-located (S4-4) to a known position relative to the iso-centre of the treatment apparatus and images of the re-located calibration sheet (100) are obtained and processed (S4-5, S4-6) to determine a transform corresponding to the relocation of the calibration sheet (100) from the first position to the iso-centre of the treatment apparatus.

Abstract: A marine harness (1) comprising a tow attachment (2), the tow attachment being such that a person wearing the harness can be towed along by way of attaching a tow line to the attachment, and the tow attachment arranged rearwardly of the harness.
