Abstract: A method for determining estimated real dimensions of an elevator car by: acquiring a virtual 2-dimensional map of the car based on data provided by a lidar sensor, the map representing reflection surfaces from which laser light emitted by the sensor is reflected; defining a rectangular starting area at a position located within the real dimensions of the car; successively extending the area by one pixel in each of four extension directions orthogonal to edges of the area, and when any pixel in one of the extension directions corresponds to one of the reflection surfaces in the map, stopping extending the area in this extension direction and successively extending the area by one pixel in each of the remaining extension directions the area is extended to a maximum in all the extension directions; and determining the fully extended rectangular area as the estimated real dimensions of the car.

Abstract: A timekeeping pivot linking a first part with a second part, pivotably about a pivot axis, the pivot comprising a blade having an edge, rigidly connected to one of the first or second parts and the median plane of which passing via the edge defines a blade plane, and a bearing area rigidly connected to the other of the first and second parts and against which the edge of the blade bears, the contact points of the blade and of the bearing area being substantially situated on the pivot axis, the first and second parts being rigidly connected in translation in the direction orthogonal to the pivot axis contained in the blade plane.

Abstract: A drive system for energizing a device that includes a bellows actuated drive. The bellows actuated drive provides linear forward and backward movement by fluid expansion and contraction of a fluid within a reservoir according to a temperature differential while the reservoir is in fluid contact with the bellows. In one variant, two bellows are configured in a V shaped conformation. Various devices are driven using the drive system of the current invention and include a timepiece, a medical device, an implantable medical device, a cardiac rhythm management device, a hearing aid, a medical micro-injector, a sensor, and a biometric transmitter.
