Abstract: Methods of squaring, in hardware logic, a floating point number comprising an m-bit input exponent and an input mantissa comprise generating a candidate mantissa output, in mantissa hardware logic, by squaring the input mantissa and generating, in exponent and exception logic, three candidate exponent outputs. The three candidate exponent outputs comprise (i) an exceptional exponent output, (ii) an exponent output generated from the m-bit input exponent and (iii) an incremental exponent generated by incrementing the exponent output. The method further comprises selecting, as the output mantissa, either the candidate mantissa output or an exceptional mantissa output based on exception signals generated by the exponent and exception logic based on the m-bit input exponent. The method additionally comprises selecting, as an output exponent, one of the three candidate exponent outputs based on the exception signals and based on a signal indicating a mantissa overflow condition.

Abstract: Methods of calculating a square of an input number in hardware logic are described. An m-bit number is received and Booth encoding is performed on different groups of three consecutive bits selected from the input to generate an encoded value for each of the groups. For each group, the method comprises forming a truncated string from the input number, generating an updated version of the truncated number and selecting a bit string based on the encoded value, the selected bit string comprising zeros or a left-shifted version of the updated version of the truncated number sign extended to a bit-width of 2m bits. The method further comprises combining the selected bit strings and square and sign bits for each group into an addition array; and summing the bits in the addition array.

Abstract: An out-the-front knife, components thereof, and associated methods. The out-the front knife can be a double-action spring-assisted knife. The knife includes a handle and a blade. The handle includes a rear end and a front opening opposite the rear end. The blade is movable with respect to the handle between stowed and deployed positions. In the stowed position, the blade is biased rearward. The knife includes an actuator movable in a deploying direction to spring the blade forward away from the stowed position toward the deployed position.

Abstract: A fan assembly is disclosed. The fan assembly can include a first support frame. The fan assembly can comprise a shaft assembly having a first end coupled with the first support frame and a second end disposed away from the first end. A second support frame can be coupled with the first support frame and disposed at or over the second end of the shaft assembly. An impeller can have fan blades coupled with a hub, the hub being disposed over the shaft assembly for rotation between the first and second support frames about a longitudinal axis. Transverse loading on the shaft assembly can be controlled by the first and second support frames.

Abstract: A light emitting user input device can include a touch sensitive portion configured to accept user input (e.g., from a user's thumb) and a light emitting portion configured to output a light pattern. The light pattern can be used to assist the user in interacting with the user input device. Examples include emulating a multi-degree-of-freedom controller, indicating scrolling or swiping actions, indicating presence of objects nearby the device, indicating receipt of notifications, assisting pairing the user input device with another device, or assisting calibrating the user input device. The light emitting user input device can be used to provide user input to a wearable device, such as, e.g., a head mounted display device.

Abstract: User interfaces for virtual reality, augmented reality, and mixed reality display systems are disclosed. The user interfaces may be virtual or physical keyboards. Techniques are described for displaying, configuring, and/or interacting with the user interfaces.

Abstract: An animal feces collection assembly for holding a plastic bag open for receiving animal feces includes a holder that has a stem portion and a ring portion. The stem portion can be gripped by a user and the ring portion can have a plastic bag positioned therearound. The ring portion has a groove integrated therein. A gasket is positionable around the ring portion such that the gasket is positioned in the groove. In this way the gasket compresses the plastic bag into the groove to retain the plastic bag on the ring portion.

Abstract: Examples described herein relate to memory thin provisioning in a memory pool of one or more dual in-line memory modules or memory devices. At any instance, any central processing unit (CPU) can request and receive a full virtual allocation of memory in an amount that exceeds the physical memory attached to the CPU (near memory). A remote pool of additional memory can be dynamically utilized to fill the gap between allocated memory and near memory. This remote pool is shared between multiple CPUs, with dynamic assignment and address re-mapping provided for the remote pool. To improve performance, the near memory can be operated as a cache of the pool memory. Inclusive or exclusive content storage configurations can be applied. An inclusive cache configuration can include an entry in a near memory cache also being stored in a memory pool whereas an exclusive cache configuration can provide an entry in either a near memory cache or in a memory pool but not both.
