Patent number: 12208934Abstract: Systems and methods are disclosed for handling items for custom-sized multi-item packages. In one embodiment, an example system may include a multi-item loading component configured to support multiple items, the multi-item loading component including a first surface, a second surface disposed at an angle with respect to the first surface, a first sidewall configured to slide in a vertical direction from a raised position to a lowered position, and a second sidewall configured to slide in the vertical direction from the raised position to the lowered position. The system may include a pusher component configured to push the plurality of items off the multi-item loading component when the first sidewall and the second sidewall are in the lowered position.Type: GrantFiled: July 31, 2023Date of Patent: January 28, 2025Assignee: Amazon Technologies, Inc.Inventors: Kristof Lambrechts, Philip Corens, Peter Van Avermaet, Matthias Martens, Jonas De Bock

Patent number: 10746712Abstract: A process for operating a gas sensor (10), which process includes a calibration of the gas sensor (10). A test gas (16) is drawn in via a pump (12) coupled with the gas sensor (10), whereby the test gas (16) is supplied to the gas sensor (10). Different volume flows are generated by the pump (12) and respective volume flow-dependent measured values (26) are detected by the pump (12). The volume flow-dependent measured values (26) are recorded together with the respective volume flow. A sensor control unit and a computer program functioning as a control program (48) are provided to implement the process.Type: GrantFiled: May 16, 2018Date of Patent: August 18, 2020Assignee: Drägerwerk AG & Co.

Patent number: 10466223Abstract: A method and system for testing a pumping device (9) with a control unit (91) in a gas-measuring system (1). The pumping device (9) is tested with the control unit (91), which is configured to test readiness of the pumping device (9) to operate. An initialization data set and an operating data set are used for the testing. An indicator of readiness of the pumping device (9) to operate is determined based on this.Type: GrantFiled: November 22, 2016Date of Patent: November 5, 2019Assignee: Dräger Safety AG & Co.

Patent number: 9945827Abstract: A method for testing a gas sensor is based on a gas-measuring system with a test gas source and with a pumping device. A predefined quantity of a gas or of a gas mixture is fed in, from the test gas source, to the gas sensor over a predefined time and metered. The response of a measured signal of the gas sensor is determined as a sensor response. Characteristic variables, from which an indicator of the ability of the gas sensor to operate is determined, are determined from the sensor response.Type: GrantFiled: November 22, 2016Date of Patent: April 17, 2018Assignee: Dräger Safety AG & Co.

Patent number: 7559228Abstract: A process is provided for measuring a gas concentration with at least one thermal measuring element. The thermal measuring element is operated by pulses. A measured value of the gas concentration in the environment of the measuring element is obtained from the evaluation of the response of the measuring element to at least one single pulse by determining transient states of the thermal measuring element. From this the measured value of the gas concentration in the environment of the measuring element can be derived, during the imposed pulse based on electric measured variables.Type: GrantFiled: August 23, 2007Date of Patent: July 14, 2009Assignee: Dräger Safety AG & Co.

Patent number: 5849591Abstract: The invention is directed to a method for determining the portion of a gaseous or vaporous component in a gas mixture utilizing a detecting substance which can enter into a chemical reaction with the component to produce a coloration of the detecting substance and utilizing a device for evaluating the coloration. The method includes the steps of: passing the gas mixture at a constant volume flow through a channel containing the detecting substance; detecting a reflectance signal I(t) within a defined spatially fixed length segment of the channel; determining a slope .DELTA.I/.DELTA.t at the start of the chemical reaction during a time interval .DELTA.t in which the detecting substance is present in excess; determining a saturation reflectance signal I.sup.100% toward the end of the chemical reaction which corresponds to an almost complete chemical conversion of the detecting substance within the length segment; and, determining a normalized slope in correspondence to the formal relationship: .DELTA.I/(I.sup.Type: GrantFiled: May 13, 1997Date of Patent: December 15, 1998Assignee: Dragerwerk AktiengesellschaftInventors: Wolfgang Bather, Ingo Kaneblei, Matthias Martens, Andreas Mohrmann, Ingo Pooch
