Publication number: 20230078152Abstract: A pump assembly for a dental cleaning appliance includes a positive displacement pump including a fluid chamber and a fluid displacement member which is moveable in a linear direction relative to the fluid chamber, and a drive for actuating the pump to draw fluid into the fluid chamber through a fluid inlet. An energy storage device converts kinetic energy generated during actuation of the pump by the drive into potential energy, and stores the potential energy. A cam is connected to the drive for rotation relative to the fluid displacement member. The cam has a ramp extending about the fluid displacement member which is engaged by a cam follower connected to the fluid displacement member. As the cam moves relative to the fluid displacement member, the cam follower moves along the ramp to actuate the pump to draw fluid into the fluid chamber, and beyond the end of the ramp to enable the energy storage device to use the stored potential energy to actuate the pump to urge fluid from the fluid chamber.Type: ApplicationFiled: February 8, 2021Publication date: March 16, 2023Applicant: Dyson Technology LimitedInventor: Christopher Graham VINCENT

Publication number: 20230084228Abstract: Measures for use in controlling a robot. At an electronic user device, data representative of an environment of the robot is received from the robot. The received data indicates a location of at least one moveable object in the environment. In response to receipt of the representative data, a representation of the environment of the robot is displayed on a graphical display of the electronic user device. Input is received from a user of the electronic user device indicating a desired location for the at least one moveable object in the environment of the robot. In response to receipt of the user input, control data is transmitted to the robot. The control data is operable to cause the robot to move the at least one object to the desired location in the environment of the robot.Type: ApplicationFiled: February 24, 2021Publication date: March 16, 2023Applicant: Dyson Technology LimitedInventors: Charles Anthony Neild COLLIS, James Trevor CLARKSON
