Abstract: A cutting device for cutting a pipe having a pipe wall. The cutting device includes an elongate carrier having a tool end which is engageable with a power tool and an opposed free end. The device includes a guide wheel located at the free end of the carrier which is loosely mounted thereon for rotation relative thereto, having a bearing surface extending parallel to a longitudinal axis of the carrier. The device also includes a cutting element having a peripheral cutting edge which is located adjacent to the guide wheel being positioned intermediate the guide wheel and the tool end. The cutting element is of greater transverse dimension than the guide wheel so that when the bearing surface bears against an internal surface of the pipe the distance between the cutting edge of the cutting element and the bearing surface enables the cutting element to cut through the pipe wall.

Abstract: Neural networks, in many cases, include convolution layers that are configured to perform many convolution operations that require multiplication and addition operations. Compared with performing multiplication on integer, fixed-point, or floating-point format values, performing multiplication on logarithmic format values is straightforward and energy efficient as the exponents are simply added. However, performing addition on logarithmic format values is more complex. Conventionally, addition is performed by converting the logarithmic format values to integers, computing the sum, and then converting the sum back into the logarithmic format. Instead, logarithmic format values may be added by decomposing the exponents into separate quotient and remainder components, sorting the quotient components based on the remainder components, summing the sorted quotient components to produce partial sums, and multiplying the partial sums by the remainder components to produce a sum.

Abstract: The technology described herein is related to a two-phase deployment-initiated wakeup mechanism for a body-mountable electronic device. During a first phase of the two-phase wakeup mechanism, a motion sensor detects an acceleration event indicative of deployment of the device onto the body of the user. During a second phase of the two-phase mechanism, control circuitry can be adapted to be enabled by the acceleration event. Once enabled, the control circuitry can verify that the device has been launched onto the body of a user via a deployment applicator in which the device is retained until deployment. Once verified, the control circuitry can wake up the body-mountable electronic device by transitioning the device from a sleep state to a functional (or operational) state.

Abstract: A well plate assembly with an interior channel system in the well plate lid provides a more efficient and uniform distribution of fluid into a receptacle positioned below the well plate lid. The channel system in the lid allows air, or other fluid, to pass through with the use of a pump to each of a plurality of channels in the receptacle. Inlet and outlet valves in the lid prevent a gasket positioned between the lid and the receptacle from releasing contact with the receptacle due to high pressure experienced during the injection of fluid into the assembly. Specifically, pressure under a specified tolerance passes through the inlet valves, and if the pressure within the channel system exceeds the limit of the outlet valve, the outlet valve opens and allows air to escape the lid safely without disturbing the fluid flow into the channels below.

Abstract: A filter base for receiving a complementary mating filter housing assembly. The filter base includes a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the filter housing assembly. The wire harness assembly includes conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The connector housing has an upper surface and an oppositely facing lower surface and is dimensioned to receive a first end portion of the one or more contacts. The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly.

Abstract: Computer-implemented methods and systems are provided for automatically performing a task on a remote computer. During a registration stage, the system receives personal information of a human user, obtains an IP address and a device configuration for a computing device, and stores the personal information, IP address, and the device configuration in record in a database.

Abstract: A System Platform establishes a Genuine User ID (“GUID”) (based upon input received from an Identity Management Source), creates a user profile for an Intended User, generates a unique data set based upon input associated with the user profile and a digital device it has registered to the Intended User, which is securely provisioned on the digital device. The output of the GUID in combination with the output of an algorithm in a provisioning application enables the digital device to respond to Access Requests at an Access Point. The response from the genuine Intended User's application on their genuine digital device produces a unique data package which combines the GUID, a device ID for the digital device and the output of the algorithm using the payload obtained from one or more data management sources.

Abstract: A cleaner head for a vacuum cleaner has a housing, an agitator mounted within the housing, and a drive mechanism for driving the agitator about a first axis A. The drive mechanism is mounted to the housing for rotation about a second axis R. The second axis R is offset from the first axis A. When the agitator is brought into contact with a surface to be cleaned, the surface exerts a reaction torque on the agitator that causes the drive mechanism to rotate about the second axis R.
