Abstract: A mopper and a cleaning handle are provided. The mopper includes a cleaning pad and a cleaning handle. The cleaning pad includes a pad body and a first connector disposed on the pad body. The cleaning handle includes a handle body, a second connector, and a slider. The second connector is connected to a first end of the handle body and configured to be fitted with the first connector in a concave-convex manner. The slider is movably sleeved outside the handle body, and the slider is configured to, in a situation that the first connector and the second connector are fitted together in the concave-convex manner, move towards the first end along a lengthwise direction of the handle body to drive the first connector to be separated from the second connector. The mopper is simple in structure, and is easy in use.

Abstract: This disclosure describes a test prediction service for predicting needed resources and associated costs for testing projects related to testing of new programs, services, etc., within a service provider network. The test prediction service uses a first machine learning model for predicting “hard costs” using data from a first data source that includes end-to-end test details such as associated resource and infrastructure use (costs) of the service provider network during previous end-to-end testing projects. A second machine learning model is used for predicting “soft costs” using data from a second data source that includes data, e.g., engineering headcount/hours spent developing the end-to-end testing and/or during previous end-to-end testing. The data is used to train the machine learning models. The test prediction service uses the trained machine learning models to generate estimated testing costs of new testing projects when a user enters project attributes for a new testing project.

Abstract: An inflatable neck traction device includes a supporting portion and a bearing portion. The height of the top surface of the bearing portion is lower than that of the supporting portion. The supporting portion has a neck support body and two shoulder abutting bodies, and can be provided therein with a first airbag and two second airbags. An inflation device can be connected to the airbags. When a user rests on the device in a supine position, the top surface of the neck support body supports the neck, and the shoulder abutting bodies abut against the shoulders. The inflation device inflates or deflates the airbags to displace the neck support body along a first axis and the shoulder abutting bodies along a second axis to change the force exerted by the neck support body and shoulder abutting bodies on the neck and shoulders to achieve cervical traction effects.

Abstract: A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.

Abstract: A body joint support device capable of abutting against at least one body joint and accommodating in configuration both to the bending and non-bending states of the body joint includes a covering structure, a control device, and at least one electrode pad unit and/or inflatable airbag. The covering structure can be worn to the body joint, the electrode pad unit is provided on the inner surface of the covering structure, and the control device is provided on the outer surface of the covering structure. The control device can transmit current to the electrode pad unit so that the electrode pad unit outputs current to stimulate and/or heat muscles. When a body joint moves, the force produced by the covering structure can press the electrode pad unit tightly against the skin at the body joint, so that the electrode pad unit does not become loose due to frequent body joint movement.

Abstract: The systems and methods described herein are for monitoring the tightness of bolts. The systems and methods may be used with a mechanism to apply a percussive tap and with a recording or monitoring device for detecting and recording the acoustic signals that are generated by the percussive tap. The acoustic signals generated by percussive taps applied to bolts in various looseness states are analyzed and a machine learning model is developed that allows for determining bolt looseness based on the acoustic signals.

Abstract: A garment structure having an adjustment mechanism for abutting at least one pad unit against a human body includes a garment body, at least one adjustment belt, and at least one pad unit being an electrode pad unit, a heating pad unit, or an electrode pad unit with a heating unit. The adjustment belt has one end connected to the garment body, and another end fixed to an outer surface of the garment body. When the adjustment belt is pulled tight, the garment body is dragged to move toward the skin. The pad unit is disposed on the garment body, and moves, along with a portion of the garment body being dragged, to abut against the skin. A user wearing the garment structure can pull and secure the adjustment belt to enable the pad unit to easily and quickly abut against the skin to proceed with electrotherapy and/or heat therapy.
