The female part has a cavity and the male part has a projection which is inserted into the cavity of the female part, both parts being coupled to each other due to the use of a retaining device together with at least one pin which at least partially crosses through the female part, the retaining device and the male part.

Abstract: A tailsitter aircraft includes an airframe having first and second wings with first and second pylons extending therebetween, a thrust array attached to the airframe, payloads and payload saddle assemblies coupled to the pylons each configured to secure a respective payload. The thrust array includes propulsion assemblies configured to transition the airframe between a forward flight orientation for wing-borne lift and a VTOL orientation for thrust-borne lift. Each payload saddle assembly includes a latch assembly and a retainer configured to secure the respective payload against a respective pylon. A latch assembly is movable between various positions including an open position and a closed position and is configured to secure the respective payload in the closed position and release the respective payload in the open position. Each latch assembly is configured to move from the closed position to the open position to release the respective payload in the VTOL orientation.

Abstract: The specification teaches an imaging system that evaluates meat quality. The imaging system includes an X-ray scanning system that generates X-ray scan data of meat and a hyperspectral imaging system that generates hyperspectral imaging data. A computing device acquires the X-ray scan data and hyperspectral imaging data, automatically determines a quality of the meat by analyzing the acquired X-ray scan data in combination with the hyperspectral imaging data, categorizes the meat, based on the determined quality, into one of acceptable quality and unacceptable quality categories; and generates data indicative of the quality of the meat.

Abstract: The present invention relates to a pin for coupling between a wear element and a support of an earth-moving machine and a coupling system, said system comprising a wear element, a support to receive said wear element and a pin to secure retention between the wear element and the support thereof. The female part is coupled to the male part, these two parts being kept coupled by means of the pin of the present invention which comprises a body, an elastic block and a latch that acts as a retention element. The pin that interacts with the latch that locks the pin in position. Said pin prevents the female part from coming out of the mounting position thereof with the male part and therefore keeps the coupling between both parts. The detachable lock enables the pin to be removed from the coupling.

Abstract: A method of operating a power converter is provided. The power converter includes a rotor side converter configured to be electrically coupled to a rotor of a wound rotor induction generator. The method includes operating the power converter in a grid forming operating mode in which the rotor side converter is operated to control an output voltage at a stator of the wound rotor induction generator in accordance with a reference stator voltage. Operating the power converter in the grid forming operating mode includes deriving, based on the reference stator voltage for the output stator voltage, a reference rotor current for a rotor current in the rotor and controlling the rotor current in the rotor in accordance with the reference rotor current.

Abstract: A device for capturing optical information configured for being installed in a recess of an exterior surface of a vehicle, comprising at least an imaging means configured for obtaining optical information of the surroundings of the vehicle. The imaging means are movable between an operating position and a non-operating position, wherein in the non-operating position the imaging means is able to be located in the recess of the vehicle. The device also comprises a protective cover configured for being able to cover the opening of the recess when the imaging means is in an operating position outside the recess.

Abstract: Exemplary embodiments of hair styling appliances having a multi-function actuator are provided herein. In general, the disclosed embodiments of hair styling appliances may include a multi-function actuator configured for adjusting settings of one or more hair appliance variables. In one embodiment, the multi-function actuator may include at least two separate actuators, which are assembled together on the hair styling appliance to look like one component, yet are configured to be actuated independently of one another. In one embodiment, the multi-function actuator may be ergonomically positioned on the hair styling appliance for easily accessible manipulation and actuation with the user's thumb. In one embodiment, the multi-function actuator may comprise a push button and dial combination. In one embodiment, the push button may be used to select temperature and/or time, and the dial may be used to adjust the temperature and/or time to a desired setting.
