Abstract: A kitchen scale, including a scale body, a magnetic attraction part arranged in the scale body, a radio module arranged in the scale body, at least one button arranged on a surface of the scale body, and a speaker arranged in the scale body. It is convenient to place the kitchen scale, and the kitchen scale is unnecessarily placed on any countertop and does not occupy any storage space.

Abstract: A bed includes: a bed body having a space for a user to rest; a monitoring device connected to the bed body, the monitoring device including a pressure detecting mechanism, a signal processing unit electrically coupled to the pressure detecting mechanism, and a monitoring unit electrically coupled to the signal processing unit. The pressure detecting mechanism is configured to detect pressure variations of the bed body, generate pressure data, and transmit the pressure data to the signal processing unit. The signal processing unit is configured to process the pressure data and generate processed signal data. The monitoring unit is configured to monitor the processed signal data.

Abstract: A weighing scale includes a scale body and a detecting board. The scale body includes a platform in contact with feet of a subject, a weighing mechanism, a signal processor, a wireless communication device, and a display screen. The detecting board is separated from the scale body and can abut against a top head of the subject and can move towards or away from the platform. At least one of the scale body and the detecting board includes a signal emitter, and at least one of the scale body and the detecting board includes a signal receiver. The signal emitter and the signal receiver measure a distance between the platform and the detecting board. The signal processor processes data of the signal emitter, the signal receiver, and the weighing mechanism, transmits processed data to the display screen and an external mobile device or server.

Abstract: A body analyzer includes a main body including a platform contacting feet of a subject, an information transmitter, a weighing and body analyzing mechanism, a signal processor, and a wireless communication device, and a detecting board abutting against the subject's top head. At least one of the main body and the detecting board has a signal emitter, and at least one of the two has a signal receiver, thereby measuring a distance between the platform and the detecting board. The information transmitter emits data of the signal emitter and the signal receiver to the weighing and body analyzing mechanism. The weighing and body analyzing mechanism calculates body compositions of the subject. The signal processor processes data from the signal emitter, the signal receiver, and the weighing and body analyzing mechanism. The wireless communication device emits a processed data to an external mobile device or server via a wireless network.

Abstract: A fuel reformer cooler for cooling a hydrogen-containing effluent released from a fuel reformer is disclosed. The fuel reformer cooler may comprise a heat transfer wall separating an effluent conduit from a coolant conduit and permitting heat transfer from the effluent in the effluent conduit to a coolant in the coolant conduit therethrough. The heat transfer wall may be formed from a base that includes a first surface facing the coolant conduit and a second surface facing the effluent conduit. The cooler may further comprise an anti-hydrogen embrittlement layer applied to the second surface of the base to shield the base from exposure to the effluent, and a plurality of symmetrical fins each extending through the anti-hydrogen embrittlement layer and contacting the second surface of the base. The plurality of symmetrical fins may project into the effluent conduit.

Abstract: A pre-chamber assembly for an engine having a cylinder head defining a coolant passage is provided. The pre-chamber assembly includes a body member defining pre-combustion chamber received within the cylinder head, and a plurality of fins projecting radially from an outer surface of the body member. The plurality of fins includes a first set of fins proximate to the pre-combustion chamber, a second set of fins spaced apart from the first set of fins along a longitudinal axis, and a third set of fins disposed between the first set of fins and the second set of fins. A number of fins of the first set of fins is greater than a number of fins of the third set of fins, and the number of fins of the third set of fins is greater than a number of fins of the second set of fins.

Abstract: A tube assembly for a beat exchanger is provided having a first U-shaped stainless steel assembly component and a second U-shaped stainless steel assembly component. In addition, the tube assembly has at least one laser-welded joint coupling the first and second U-shaped assembly components together. The laser-welded joint has a weld that extends along substantially an entire length of the tube assembly.
