Title: Device for tensioning a canvas on a frame
Inventor: ROY FRANCOIS
IPC: A47G1/10
Filed: 2019-01-30
Abstract: A device for stretching a canvas mounted to a frame comprises a spacer and a screw. The frame has a plurality of side members each mutually abutting at angled ends. A first portion of the spacer includes a central aperture therethrough and two opposing ends or sides. Each end of the first portion is sized to engage a contact surface of each side member. The screw has a threaded shaft adapted for rotational engagement with the central aperture of the first portion of the spacer. The threaded shaft terminates at a first end thereof with a screw head that has a frustoconical side wall and an end surface that includes a tool-engaging recess. Rotating the screw to move the screw head closer to the spacer causes the spacer to push the side members mutually away from each other to stretch the canvas.

Abstract: Apparatus and methods for unified high-bandwidth, low-latency data services provided with enhanced user mobility. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Wideband amplifier apparatus are used to support delivery of the sub-bands to extant HFC network nodes (e.g., hubs or distribution points) within the network. Premises devices are used to provide the 5G-based services to users at a given premises and thereabouts. In another variant, local area (e.g., "pole mounted") radio devices are used to provide supplemental RF coverage, including during mobility scenarios.

Abstract: A playback application is configured to dynamically generate topology for an interactive media title. The playback application obtains an initial topology and also collects various data associated with a user interacting with the feature. The playback application then modifies the initial topology, based on the collected data, to generate a dynamic topology tailored to the user. The dynamic topology describes the set of choices available to the user during playback as well as which options can be selected by the user when making a given choice. In addition, the playback application also selectively buffers different portions of the interactive media title, based on the collected data, in anticipation of the user selecting particular options for available choices.
Patent CA-3107045-A1 (CA)
Inventor: PAUL EBERHARD
IPC: F28F3/04
Filed: 2019-08-03
Abstract: The invention relates to a heat exchanger plate with a triangular profile, wherein the triangles (D1, D2 and D3, D4) connect each plate together with a base line (B) and the triangles of the two adjacent plates (1, 2) point towards each other with their tips and stand on the base line (B) of the other plate. In a second profile shape, the triangles are replaced by a profile shape that resembles a house (6) with a pitched roof (8). The profile elements (y, z) which protrude into the area of the "condensate tray" (x) can be shortened by ? h in the area where the condensate forms to improve condensate drainage. This reduces the adhesion forces, as a result of which the condensate can drain away better. The profiles can also have a zigzag shape (seen in the direction of flow).
