The base portion may include one or more audio speakers and/or storage compartments and/or charging pads configured for wirelessly charging an electronic device.

Abstract: Surgical systems and methods involving a reamer tool and a surgical robotic arm. The reamer tool has a shaft, a tool engagement surface coupled to the shaft, and a reamer head attached to the shaft. The surgical robotic arm supports a guide that can receive the reamer tool. The guide has a pair of arms, each arm extending to an arm end and the arm ends being spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms. The guide enables a portion of the shaft to move through the opening between the arm ends such that the shaft portion can enter and exit the channel. The arms define a guide engagement surface that is arc-shaped and that enables contact with the tool engagement surface to facilitate alignment of the reamer tool and the guide.

Abstract: Aspects of the present disclosure include methods for generating a sampled profile including a plurality of sampling points having a plurality of characteristic values associated with the detected non-visible light, identifying one or more macroblocks each includes a subset of the plurality of sampling points, calculating a number of occurrences of the local pattern value within each subset of the plurality of the sampling points for each of the one or more macroblocks, generating a first array including a plurality of weighted values by calculating the plurality of weighted values based on the numbers of occurrences of the local pattern value and corresponding sizes of the one or more macroblocks, assigning a unique index to each of the plurality of weighted values, generating a second array of the unique index by ranking the plurality of weighted values, and generating a third array including a plurality of ranking distances.

Abstract: Provided are novel Pyrazolopyrimidine Derivatives of Formula (I): and pharmaceutically acceptable salts thereof, wherein R1, R2, R3, and R4 are as defined herein. Also provided are compositions comprising at least one Pyrazolopyrimidine Derivative, and methods of using the Pyrazolopyrimidine Derivatives for treating or preventing a herpesvirus infection in a patient.

Abstract: A computing device provides enhancement of the capabilities of text messaging applications that execute on user devices. The computing device includes a processor that receives a text message via a network from a user device, the text message including a character representation of a product bundle of a merchant. The processor determines bundle data for the product bundle by referencing a database using the character representation. The processor provides one or more text messages via the network to the user device with transaction data including the bundle data, payment data, and shipping data. The processor receives a text message via the network from the user device confirming the transaction data. The user may use text commands presented by the computing device or natural language conversation in the text messages to the computing device to modify the transaction data and perform other ecommerce actions.
