Abstract: In brief, the invention relates in particular to a converter (100) comprising a plurality of rectifier arms (110), making it possible in particular to rectify AC electrical signals available on the electrical phases (U, V, W) of an electrical grid. To balance the electrical signals coming from the electrical phases (U, V, W) of the electrical grid, and to limit a modulation amplitude of the DC signal generated by the converter (100) between its output terminals (S1, S2), the converter (100) also comprises a correction arm (120) that determines an amplitude of electric current flowing in a neutral (N) of the electrical grid and that generates an opposing electric current of equal or if not close amplitude. The invention also relates to a two-way charger (10) comprising such a converter (100) and one or more active double bridges (200), such that an output (S3, S4) of the active double bridges (200) is electrically isolated from the converter (100).

Abstract: A maintenance control panel connected to an elevator control system controls displacement movements of an elevator car through actuation of activation, downward direction button and upward direction buttons. Each button has an actuation element displaceable in an actuation direction to change from an unactuated to an actuated actuation state when displaced beyond an actuation position and outputs an actuation signal representing the actuation state. At least one of the buttons has a position sensor detecting a current position of the actuation element and outputs a position signal representing the detected position. The elevator control system responds to the position signal to control a power supply to a drive motor and thus a displacement speed of the car. A maintenance technician can control the displacement speed intuitively, depending on how hard the button with the position sensor is pressed, to avoid an abrupt start or braking of the car.

Abstract: A dispensing station comprises beneficial products for patients of a health care provider. An inventory database tracks inventory available in the dispensing station. A patient is associated with a prescription record, which specifies a prescribed beneficial product. The patient may provide patient identifying information to the dispensing station, such as credentialed payment information, which may be used to identify a prescription record, authenticate the patient, transfer a payment, and/or dispense the prescribed beneficial product to the patient. The prescription record may be valid for a limited time period, may be restricted to fulfillment within a particular location, and/or may be restricted to one or more specified dispensing stations. The dispensing station may validate the beneficial products before dispensing the products to the patient.
