Abstract: System, devices, and methods for repositioning a patient from a first surface to a second surface are disclosed herein. An exemplary system can include a housing, a cartridge removably coupled to the housing, and a transfer sheet. The cartridge includes a first roller rotatably mounted along a first axis and a second roller rotatably mounted along a second axis parallel to the first axis. The transfer sheet includes a first end portion coupled to the first roller and a second end portion coupled to the second roller. The transfer sheet has a fold defining a top layer between the fold and the first end portion and a bottom layer between the fold and the second end portion. The top layer is configured to contact the patient, and the bottom layer is configured to contact the first surface and the second surface.

Abstract: Apparatus and methods for positioning a body part of a patient. An apparatus can comprise a portable support structure configured to be placed on a patient support surface under a body part of a patient and retention elements attached to the support structure. At least a portion of the support structure is configured to move from lowered position to a raised position above the lowered position. The retention elements are configured to receive the body part. Each retention element has a holding portion and an open region, and each retention element faces at least partially sideways in a retention position.

Abstract: An electric drive module that includes a housing, a pair of drive units and a coupling unit. The drive units are disposed in the housing and each drive unit includes a motor unit and a friction brake. The motor unit has a stator, which is non-rotatably coupled to the housing, and a rotor that is rotatable about a motor axis and configured to drive a wheel of a vehicle. The friction brake has a first portion, which is non-rotatably coupled to the housing, and a second portion that is drivingly coupled to the rotor. The friction brake can be operated to create a rotational drag force that resists rotation of the second portion relative to the first portion. The coupling unit is configured to selectively rotatably couple the second portions of the friction brakes to one another.

Abstract: A method and system is provided for repositioning a patient on a transfer surface (e.g., a hospital bed, a stretcher, an imaging system, or the like). The system comprises two rollers positioned on one side of the surface, and a retractable transfer sheet wound around the rollers. The transfer sheet may be unwound from the two rollers to form two layers between the patient and the transfer surface. The patient may then be moved by sliding a top layer of the transfer sheet relative to a second layer of the transfer sheet. After use, the sheet can be retracted around the roller(s), allowing it to be stored in a location that is convenient but out-of-the-way. Such a system may allow a patient to be moved with less force, in less time, with fewer personnel, or with some other benefit.

Abstract: Methods and systems for real-time engine control optimization are provided. A value of an engine performance variable is determined, a value of a first operating condition and a value of a second operating condition of a vehicle engine are detected, and initial values for a first engine control parameter and a second engine control parameter are determined based on the detected first operating condition and the detected second operating condition. The initial values for the first engine control parameter and the second engine control parameter are adjusted based on the determined value of the engine performance variable to cause the engine performance variable to approach a target engine performance variable. In order to cause the engine performance variable to approach the target engine performance variable, adjusting the initial value for the first engine control parameter necessitates a corresponding adjustment of the initial value for the second engine control parameter.

Abstract: Methods and systems for engine control optimization are provided. One or more operating conditions of a vehicle engine are detected. A value for each of a plurality of engine control parameters is determined based on the detected one or more operating conditions of the vehicle engine. A range of the most commonly detected operating conditions of the vehicle engine is identified and a region of optimization is defined based on the range of the most commonly detected operating conditions of the vehicle engine. The engine control optimization routine is initiated when the one or more operating conditions of the vehicle engine are within the defined region of optimization.

Abstract: Methods and systems for optimizing a performance of a vehicle engine are provided. The method includes determining an initial value for a first engine control parameter based on one or more detected operating conditions of the vehicle engine, determining a value of an engine performance variable, and artificially perturbing the determined value of the engine performance variable. The initial value for the first engine control parameter is then adjusted based on the perturbed engine performance variable causing the engine performance variable to approach a target engine performance variable. Operation of the vehicle engine is controlled based on the adjusted initial value for the first engine control parameter. These acts are repeated until the engine performance variable approaches the target engine performance variable.

Abstract: Methods and systems for engine control optimization are provided. A first and a second operating condition of a vehicle engine are detected. An initial value is identified for a first and a second engine control parameter corresponding to a combination of the detected operating conditions according to a first and a second engine map look-up table. The initial values for the engine control parameters are adjusted based on a detected engine performance variable to cause the engine performance variable to approach a target value. A first and a second sensitivity of the engine performance variable are determined in response to changes in the engine control parameters. The first engine map look-up table is adjusted when the first sensitivity is greater than a threshold, and the second engine map look-up table is adjusted when the second sensitivity is greater than a threshold.
