A portable lighting tower includes a frame, an adjustable mast, multiple legs, a controller, and a battery pack. The adjustable mast is coupled to the frame and includes a light. The multiple legs each include an actuator operable to deploy and retract the respective leg. The controller is operatively coupled to the light and the actuators and configured to control operation of the light and the actuators. The battery pack is electrically coupled to the controller, the light, and the actuators. The light is dimmable between a maximum setting and a minimum setting, and the controller operates each of the linear actuators to deploy or retract the respective leg response to a user input.

A self-orienting sensing system for a heating, ventilation, and air conditioning (HVAC) system includes a housing having a main body. The housing defines a sensing aperture in a first portion of the main body and a mounting channel in a second portion of the main body. The self-orienting sensing system includes a sensing element retained within the housing. The sensing element is configured to detect leaked refrigerant that enters the housing via the sensing aperture. The self-orienting sensing system also includes a mounting retainer configured to extend through the mounting channel and couple the housing to an interior surface of an air handling enclosure of the HVAC system. The mounting retainer enables the mounting channel to rotate about the mounting retainer to automatically align the sensing aperture in a target sensing orientation based on a weight of the housing under the force of gravity.

A method for providing center-of-gravity information by using an image, and an apparatus therefor are disclosed. A method for providing center-of-gravity information, according to one embodiment of the present invention, comprises: generating multi-angle two-dimensional poses corresponding to a user's pose on the basis of images of the user captured at multiple angles; generating a three-dimensional pose by combining the multi-angle two-dimensional poses; generating, on the basis of the three-dimensional pose, a heatmap visually showing the pressure distribution of soles; extracting the center point of gravity on the basis of the heatmap; and providing center-of-gravity information corresponding to the user's pose by using a weight balance calculated on the basis of the center point of gravity.

A shelf bracket assembly mounted upright on a vertically disposed shelf has: a load cell; an anchor; and a cantilever supporting a shelf panel. The cantilever projects from the shelf upright in a substantially horizontal direction. The cantilever has a vertically disposed frame or a vertically disposed metal plate and a mount for the load cell. The load cell has a monolithic measuring body that has: a force-supporting section; a force-introduction section; and a linkage section between the force-supporting section and the force-introduction section. The force-supporting section of the monolithic measuring body is laterally attached to the mount. The monolithic measuring body has at least one mounting hole through which the monolithic measuring body is attached to the mount with a screw extending horizontally through the monolithic measuring body.

Various examples are directed to systems and methods for operating a vehicle comprising a tractor and a trailer attached for pulling behind the tractor. A center-of-mass system may determine a mass of the trailer and a tractor understeer. The center-of-mass system may determine the tractor understeer using steering input data describing a steering angle of the tractor and yaw data describing a yaw of the tractor. The center-of-mass system may determine a load center of mass using the tractor understeer and a mass of the trailer. The center-of-mass system may further determine that the load center of mass transgresses a center-of-mass threshold and send an alert message indicating that the load transgresses the load center-of-mass threshold.

Provided is a robot hand including: gripping portions disposed with spacings between each other in a circumferential direction about an axis, and that grip a workpiece; driving portions, each of which is provided so as to correspond to one of the gripping portions, cause the corresponding gripping portions to be linearly moved in closing directions in which the gripping portions are brought close to the axis and opening directions in which the gripping portions are moved away from the axis; and a center-of-gravity detecting unit detects a center-of-gravity position of the workpiece being gripped by the gripping portions. Each of the driving portions adjust, based on the center-of-gravity position of the workpiece, the position of the corresponding gripping portion in a direction in which the center-of-gravity position is brought closer to the axis.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A method for identifying at least one physical characteristic of a work piece includes selecting at least one test scheme having one or more test configurations. At least one error isolation scheme is selected having one or more counterpart test configurations. The work piece is moved through the one or more test configurations, and a sensor suite measures one or more of base force, torque, or motion. The work piece is moved through the one or more counterpart test configurations, and counterpart force, torque or motion are measured. Identification of the at least one physical characteristic includes isolating error common to one or more of the measured base and counterpart force, torque or motion, and removing the isolated error from the base measurements to generate one or more of refined force, torque or motion. The at least one physical characteristic is determined according to the one or more refined values.

Force-detecting sensors are installed in a motorcycle's handlebars, footpegs and seat to detect the rider's grip, weight and weight distribution. A control unit interprets the signals from the sensors to determine an attribute of the rider or an intention of the rider to make a manoeuvre. Signals from environmental sensors are used by the control unit to determine whether the intended manoeuvre would endanger the rider, and, if so, the rider is alerted before the manoeuvre is undertaken. The alert is provided before the rider notices the hazard, or before the rider reacts to the hazard. By giving advance warning, of as little as a fraction of a second, a rider is given extra time to avert a potential accident. The control unit also controls settings of the motorcycle during a hazardous state of the motorcycle.

A method is used to determine an object weight of at least one object for refrigeration positioned on a weighing area with weighing plates of a household refrigeration appliance. The respective weights are measured in a time-resolved manner by means of the weighing plates and a sum of changes in weight determined within a predetermined period of time on the weighing plates is assigned to an object for refrigeration as its object weight. A refrigeration apparatus has a household refrigeration appliance with a refrigerating zone, which has a weighing area with a number of weighing plates. The refrigeration apparatus is configured to carry out the method.
