Title: Computer-aided techniques for automatically generating designs that reflect design intents
Inventor: WANG YI
IPC: G06F30/12
Filed: 2023-03-03
Abstract: In various embodiments, an intent-driven layout application automatically generates design for floor spaces (390). The intent-driven layout application generates a logic formula (250) based on a statement of a design intent (220) and at least one fuzzy geometric predicate (230). The intent-driven layout application computes, for a first spatial object, a set of desirability values (380) for a set of candidate placements (342) within a first design based on the logic formula. Based on the set of desirability values (380), the intent-driven layout application selects a first candidate placement from the set of candidate placements (342). Subsequently, the intent-driven layout application generates a second design based on the first design, where the first spatial object has the first candidate placement within the second design.

Abstract: Reference prediction mode values, also referred to as most probable modes or MPMs, usable for encoding or decoding of a prediction mode related to a current coding unit, are derived. By deriving three MPMs instead of two for comparison with the prediction mode of the current coding block the coding efficiency is improved. This is due to the increase in the probability that the prediction mode of the current coding block corresponds to one of the derived most probable modes.

Title: Presence detection
Inventor: PETTERSEN MATTIS
IPC: F24F11/64
Filed: 2023-05-31
Abstract: A method of estimating occupancy of a room, comprising: acquiring a plurality of measurements of an aspect of air quality in the room; and estimating the occupancy of the room based on the plurality of measurements and a room ventilation rate parameter. By estimating the occupancy of the room based on aspects of air quality, it is possible to detect occupancy based on data from sensors which may already be present for other purposes (e.g. for measuring and monitoring the air quality within the room). Combining measurements of air quality with knowledge related to ventilation rate in the room results in information indicative of (or dependent upon) the occupancy of the room. Estimating the number of people in the room allows much more detailed analysis and control to be undertaken, e.g. it can be used to analyse which parts of a building (or floor) are most used and which are least used. Such occupancy data can also be used to control other services, e.g. to control the ventilation or to provide information about the number of people present (e.g. for catering or for security or safety analysis).

Abstract: Described herein are examples of tool based welding technique monitoring systems that provide an inexpensive, intuitive, and relatively robust way of tracking an orientation of a welding-type tool, and providing welding technique feedback based on the orientation. The system requires no sensors apart from a simple and/or relatively inexpensive sensor module that can travel with the welding-type tool, which makes the system highly portable. The system can also provide some feedback with minimal calibration, which can be valuable in situations where an operator forgets, or is unwilling, to take the time to fully calibrate the system. Additionally, full calibration of the system can be accomplished with a fast, simple, intuitive calibration technique.

Abstract: Dans un appareil a decharge electrique, tel qu'un laser a gaz, dans lequel une decharge a lueurs et produite dans un gaz entre deux electrodes (1, 2), au moins un element de pre-ionisation (5, 6) est place pres de l'espace de decharge et s'etend entre les electrodes de sorte que le courant passe dans l'element qui est en un materiau de resistivite intermediaire tel qu'un materiau semi-conducteur cristallin. On obtient comme resultat la pre-ionisation de l'espace de decharge qui contribue a l'initiation de la decharge principale. La pre-ionisation est due a la formation de nombreux petits arcs entre les electrodes et l'element et a la production de lumiere ultraviolette qui en resulte.

Abstract: A circuit arrangement for determining the connection condition of a plurality of subscriber lines in a telecommunication network, each of the subscriber lines having two wires extending between a subscriber station and a subscriber line interface circuit and being connected via respective resistors to the two poles of a DC voltage source. For a group of such subscriber lines the operating conditions are consecutively monitored by sampling the voltage occurring at two sampling points of both wires by a respective multiplexor and passing it to a comparator having inputs which are temporarily inter-connected by filter capacitors each separately associated with a respective subscriber line interface circuit. In addition, the comparator receives a reference voltage determining a threshold voltage. For ground key indication one of the sampling points is connected to one input of a further comparator which second input is supplied by a corresponding further reference voltage. The output signals of both comparators are presented at a central control unit for evaluation. When monitoring a ground key indication the output signal of the second comparator, however, is passed only if presupposed signals indicating correct operation, i.e. closed loop condition are present.

Abstract: The invention is a sealed thermal energy storage container (11) including front and rear walls (12,13) which together are partially absorptive and partially transmissive of visible light with a transmittance in the range between 4% and 85% and an absorptance of at least 9%. Retained within the container (11) between the front and rear walls (12,13) is an at least partially light transmissive energy storage substance (15) that experiences a liquid-solid phase change between 45°F and 190°F. After being strategically positioned for exposure to solar radiation, the energy storage substance (15) accumulates a substantial quantity of energy when changed to a liquid state by incident sunlight and subsequently releases that energy when again freezing. In addition to sequentially and alternatively storing and releasing thermal energy, the container-device (11) transmits a predetermined level of incident sunlight. Furthermore, the partially absorptive walls (12,13) are heated by sunlight and function as efficient sources of heating for the retained energy storage substance (15).
