The invention relates to a method for using a cushion, in particular for a chair, said cushion having a first cushion element (6) that can be moved with an associated degree of freedom. In said method, a sensor (98a, 98b, 98c, 98d) integrated into the cushion is used to sense the position or the change in position relative to at least one first cushion element (6), with respect to at least one degree of freedom associated with said element. The sensor (98a, 38b, 98c, 98d) is coupled to an interface (93) for the wireless output of measured values. The sensor (98a, 98b, 98c, 98d) senses measured values and sends at least some of the measured values over the interface (93) to a device (70, 80) outside the cushion, said device (70, 80) receiving and evaluating the measured values and emitting an output signal.

A chair device, a mattress device, and a propping device are provided. The chair device includes a support stand, a seat module disposed above the support stand, a connection module disposed at one side of the seat module, a back support module connected to the connection module and disposed at one side of the seat module, a first pressure adjustment module disposed in the seat module, a second pressure adjustment module disposed in the back support module, a first pressure sensing module disposed in the seat module, a second pressure sensing module disposed in the back support module, and a control module. The control module adjusts the first pressure adjustment module according to first sensed pressure signals from the first pressure sensing module, and adjusts the second pressure adjustment module according to second sensed pressure signals from the second pressure sensing module.

A tableware washing device and a method of washing tablewares are provided. The tableware washing device includes: a casing including a first accommodating space, which is used for accommodating at least one tableware for performing a washing process, a carrying module disposed in the casing, a control module, a first cleaning module disposed on an inner side of the casing and electrically connected to the control module, and a first image capture module electrically connected to the control module and disposed in the casing. The first cleaning module includes a plurality of first cleaning units that respectively provide a plurality of cleaning jets to clean the at least one tableware. The control module determines whether or not the at least one tableware is clean through a plurality of first cleaning procedure image informations captured by the first image capture module.

A waste storage device and an intelligent management system are provided. The waste storage device includes: a casing, a control module disposed in the casing, a microphone module disposed on an outer surface of the casing, and a moving module electrically connected to the control module. The microphone module is electrically connected to the control module. When the microphone module receives a first audio signal, the microphone module transmits the first audio signal to the control module, the control module analyzes an audio sending direction of the first audio signal, and the control module provides a driving signal to the moving module according to the first audio signal to drive the waste storage device to move in the audio sending direction.

An inflatable meditation device comprising a combination of a mat or leg portion and a pillow or seat portion, wherein the mat and seat are individually inflatable and are removably connectable to form a travel mediation device with the seat portion being raised above the mat portion.

A methane conversion device comprises a reaction chamber; a sensor for detecting the presence of methane; blowing means for directing external gasses Into the reaction chamber when the sensor detects the presence of methane above a predetermined threshold; conversion means that are configured to oxidise methane; and positioning means for positioning the device on an animal.

An inflatable seat cushion apparatus for comfort and pain prevention includes a cushion bladder having a bladder front side, a bladder back side, a bladder top side, a bladder bottom side, a bladder left side, and a bladder right side defining a bladder inside. A pump is coupled to the cushion bladder. The pump is coupled to the bladder left side within the bladder inside and has an intake vent and a power switch extending through the bladder left side. The power switch activates the pump to inflate the bladder inside. A release valve is coupled to the cushion bladder and extends through the bladder left side to selectively deflate the bladder inside. A pair of foam wings is coupled to the cushion bladder. The pair of foam wings is coupled to the bladder top side adjacent the bladder left side and the bladder right side.

A motorized inflatable raft includes independently controllable propellers to propel the raft. The propellers are part of a propeller control assembly that includes a power source and a joystick for control. Direction of motion is controlled by rotating independent propeller control assemblies using a joystick controller. Power is supplied by batteries in a battery housing, and application of power to the propellers is controlled by the joystick. Assembly is simplified using an easily screwed screw cap that securely fastens a battery housing that is connected through tubing to the propeller to the joystick controller.
