Abstract: Methods, systems and apparatus for providing a notification of a wet floor are provided. A scrubbing robot for scrubbing a floor and having one or more liquid carrying components has a sensor coupled to it positioned for collecting data about an area of the floor proximate to the scrubbing robot and along a path over which the robot has travelled. An application is stored on the computer for determining that liquid is on the floor by analysing the data for a presence of a second set of parameters corresponding to or crossing (from above to below or from below to above) a set of threshold parameters that is indicative of the presence of liquid on the floor. A notification module coupled to the scrubbing robot issues at least one of a human detectable and a computer detectable notification in response to the application determining that liquid is on the floor.

Abstract: A smart display screen that is reversibly rigidly attachable to a door or panel of a semi truck trailer. The smart display screen is linked to a computer and wireless modem that is built into a special frame and cabinet that is reversibly rigidly attachable to a door or panel on a semi truck trailer. The smart display screen is used to display motion video advertisements and still frame advertisements that are seen by other drivers on the road or highway. The special frame and cabinet is reversibly rigidly attachable to a door or panel of a trailer using the special mechanical clamping mechanism which allows the smart display to be easily installed onto any existing trailer door or panel by simply cutting a rectangular hole in the trailer door or panel and then installing the special frame and cabinet.

Abstract: A cooling assembly for an electric machine is disclosed. The cooling assembly may include a generally cylindrical cooling jacket for receiving a shaft, a rotor and a stator. Further, the cooling jacket jacket may be disposed in an electric machine housing. Additionally, the cooling assembly may include at least two first passages in the cooling jacket for circulating a first coolant and at least one second passage in the cooling jacket for circulating a second coolant, the second passage being disposed between the at least two first passages. Further, the cooling assembly may include a third passage on an exterior of the machine housing, the third passage extending through the housing to fluidly connect the at least two first passages and bypass the second passage.

Abstract: An actuator sub for generating hydraulic pressure having a sub housing which includes (i) an outer surface, (ii) a main flow passage extending though the sub housing, and (iii) a wall space formed between the main flow passage and the housing outer surface. At least a first hydraulic tube is position in the wall space and an equalization port is configured to transmit pressure in the main flow passage to the first hydraulic tube. A drive motor driving an bi-directional hydraulic motor, are positioned in the first hydraulic tube, with the hydraulic motor being configured to output fluid to a fluid outlet of the first hydraulic tube, and the hydraulic motor, when not under power, allowing the reverse flow of fluid through the hydraulic motor. The actuator sub includes the absence of a check valve along a path carrying fluid between the hydraulic motor and the outlet of the second hydraulic tube.

Abstract: FIG. 2 shows an MFA/2FA system (50) in which a computer (52) is tasked with simultaneously implementing one and generally many robotic process automation “RPA” functions. To achieve secure log-in to a server (54) that provides a gatekeeping function to data required for or deliverable by the RPA functions, a security bot (58) having an independent address is initially authenticated as a valid secondary device associated to a different address of a specific task-executing bot (56) that performs a specific RPA function. A token generating algorithm (62) providing synchronised tokens relative to the server (54) is linked, during a set-up procedure, to the address of the security bot (58) such that, when the task-executing bot is challenged by the server during log-in, a token (74) can be obtained by the task-executing bot (56) from the token (74) generating algorithm (62). The task-executing bot (56) is arranged to supply, i.e.

Abstract: Systems, methods and devices are described providing a selective hydraulic or electrically powered prime mover that is a bi-directional power unit system, including movement within a device used to compress and/or expand a fluid and provide fluid movement. The use of a hydraulic power unit is involved and comprises at least a pump or other fluid moving device, a first set of selective control valves delivering pressurized fluid to the device(s), and a second set of selective control valves returning unpressurized fluid from the device(s), a reservoir comprising a compensator tank, a port for operation at ambient pressure, and a pressure measuring device measuring ambient pressure allowing for unbalanced flow to and from the device as well as thermal expansion or compression. The use of a multiport and in some cases a swashplate pump that incorporates the features and functions of several valves for the system is also described.

Abstract: Methods, systems, and techniques are disclosed for selecting and dispatching a worker to assist a robot. The system may include a computer comprising a processor and a computer readable memory. The computer readable memory may include lists of worker criteria items for a plurality of workers and a list of assistance criteria items for a robot. The system may include a triggering application executable by the processor for identifying triggering data corresponding to a triggering item within sensor data from the robot. A ranking application may also be stored on the computer and may be executed in response to an identification of triggering data corresponding to the triggering item. The ranking application may be operable to cross-reference the worker criteria items on each of the first lists with the assistance criteria items on the second list and to generate a ranking of the plurality of workers based on the cross-referencing.
