  • Publication number: 20250065209
    Abstract: The golf aid disclosed herein includes a shell of rigid construction that engages the portion of the arm including distal posterior portions of a forearm, posterior portions of a wrist, and a back of a hand proximal to knuckles while leaving a palm and a thumb exposed. The shell is configured to control a wrist throughout a golf stroke by maintaining the wrist in a neutral position to prevent flexion and extension of the wrist during a golf stoke. Related methods of use of the golf aid may include wrapping a material about a portion of an arm and allowing the material wrapped about the portion of the arm to transform into the rigid state while gripping a golf club and maintaining the distal portions of the forearm, the wrist, the hand, and the golf club in alignment. The methods may include the step of maintaining the wrist in a neutral position thereby preventing flexion and extension of the wrist by engaging the shell with the arm while performing a golf stroke.

  • Publication number: 20250057611
    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.

  • Publication number: 20250053955
    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.
