Abstract: Disclosed are devices, components and methods associated with a body fluid analysis system, which, according to some embodiments, can be employed in at-home, clinical, medical office and outpatient settings and applications. The system can be configured to provide results within a short period of time after a body fluid sample has been acquired from a patient such as by a finger or skin prick. In some embodiments, a body fluid sample cartridge is configured for use in conjunction with a corresponding spectroscopic body fluid analysis device, where the cartridge comprises one or more body fluid dispersing sheets, layers or membranes. In some embodiments, the cartridge is configured to deliver and disperse a predetermined amount or volume of a body fluid sample taken from a human or animal onto, into, through or across the body fluid dispersing sheet, layer or membrane disposed within the cartridge for subsequent analysis of the body fluid sample by a corresponding spectroscopic device.

Abstract: The invention provides a computer-implemented method of planning a path for a mobile robot such as an autonomous vehicle in the presence of K obstacles. The method uses, for each of the K obstacles, a shape Bk and a density function pk(x) representing the probabilistic position of the obstacle. The method repeats the following steps for at least two different paths A:—choosing a path A, where A is the swept area of the robot within a given time interval; and—calculating based on the density function of each obstacle and the swept path an upper bound on the total probability of at least one collision FD between the robot and the K obstacles. This allows a number of candidate paths to be ranked for safety. By precomputing factors of the computational steps over K obstacles, the computation per path is O(N), and not O(NK). A safety threshold can be used to filter out paths below that threshold.

Abstract: The disclosure relates to a communication protocol method and device which enables, for example, the live feed of data from sensor nodes in a Wireless Personal Area Network (WPAN) to a centralized node, in particular for low-power long-range communications, further in particular with frequency chirp modulations. The disclosure provides long range communication with very low power consumption, preferably with a refresh rate of a few seconds per node while operating in the Licensed-Free Industrial/Scientific/Medical (ISM) frequency band, defined by the International Telecommunication Union (ITU). The method and device protocol include Medium Access Control (MAC) and Host functionalities that make the best use a LoRa radio, while keeping a reliable live feed of data from peripheral nodes to a central node, that is capable of managing multiple links, configured to comply with directives from Conformité Européenne (CE) and Federal Communications Commission (FCC) for the license-free radio frequency ISM bands.

Abstract: Method for producing a surface of revolution of a clock or watch component comprising a step of machining, with a femtosecond laser beam, a first surface of the clock or watch component so as to obtain a second surface, in particular so as to obtain a second surface whose roughness Ra is less than 100 nm, or less than 70 nm, and then a tribofinishing step applied to the second surface so as to obtain the surface of revolution.

Abstract: A process for decorating a timepiece component, which includes performing (i) engraving (E10) of a surface to be decorated of the timepiece component with a femtosecond laser; and (ii) structuring (E20) of said surface to be decorated of the timepiece component, these two decorations being at least partially superposed on each other.

Abstract: The invention relates to a method comprising a step (E0) of forming a body provided with a cavity on a face of said body, a treatment step (E2) consisting of forming, on said body, at least one reinforced adhesion area which is at least partially outside the cavity, and a step (E3) of depositing composite material. During the deposition step (E3), the cavity is filled and the reinforced adhesion area is covered with the composite material.

Abstract: A horology component (1) for a timepiece, including a first portion (10) and a second portion (20), the first portion (10) comprising one part that is at least partially transparent and at least partially superposed on top of the second portion (20), this second portion (20) taking the form of a massive portion comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and the at least partially transparent part of the first portion allowing an emission light wave emitted by the second portion (20) to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion (10) is backlit by an emission light wave emitted by the second portion (20).

Abstract: A process for decorating a dial includes a step (E1) of engraving a pattern in a pad-printing cliché with a femtosecond laser, then a step (E20) of transferring said pattern to the dial using the pad-printing cliché. The process can include surface structuring of the dial, then transferring the pattern to the dial at least partially superposed on surface-structuring obtained by the surface structuring, and can also include an intermediate coloring of the decorated or to be decorated surface in the surface structuring, using a different color from the color used in the transferring.
