Publication number: 20250195154Abstract: A user interface for a surgical system is configured to proceed through a plurality of modes and display a current mode among the plurality of modes. Each of the plurality of modes is associated with one or more sub-modes, and the user interface is configured to proceed through the plurality of modes and the plurality of sub-modes in sequence. The user interface is configured to automatically generate an image from an image source for each of the modes and sub-modes and overlay one or more markers on the image along with instructions to the user. The user interface is configured to provide a control panel comprising plurality of frequently used user inputs below a centerline of a display for ergonomics, and to highlight a current mode of the sequence on a display relative to the other modes to show progression through the sequence of modes.Type: ApplicationFiled: December 30, 2024Publication date: June 19, 2025Applicant: PROCEPT BioRobotics CorporationInventors: Mark BAERENRODT, Kee Sook JEON, Peter BENTLEY, Thomas SWYST, Lynne SMITH, Angela ZHOU, Yucheng ZHANG, Lewis CHEN

Publication number: 20250195167Abstract: A user interface comprising a touch screen display can be placed above a patient. An arm allows a user to place the user interface above the patient and provide inputs related to treatment. The arm is configured to place the display above the patient in relation to a probe inserted into the patient and view an image shown on the display, which can facilitate movement of the probes in response to the image shown on the display. The probe is located below the display, and the user is able to reach and adjust the probes while viewing images on the display. The user interface is configured with an image display area and a control panel, in which the control panel is located below the image display area, which allows the user to readily provide inputs to user interface while viewing the display and manipulating the one or more probes.Type: ApplicationFiled: December 13, 2023Publication date: June 19, 2025Applicant: PROCEPT BioRobotics CorporationInventors: Mark BAERENRODT, Yucheng ZHANG, Peter BENTLEY, Angela ZHOU, Lewis CHEN, Kee Sook JEON, Lynne SMITH

Patent number: 11589797Abstract: Embodiments of the presently-disclosed subject matter include methods and systems for measuring a level of a neurotransmitter in a subject. Embodiments of the present methods comprise displaying a fixation point, a reward target, and a non-reward target, and measuring one or more saccade movement parameters for reward saccades and non-reward saccades. The saccade movement parameters can include velocity, amplitude, reaction time, or a combination thereof. The present methods can further include determining a reward modulation of the subject, the reward modulation being equal to a difference between the reward and the non-reward values for a respective saccade movement parameter. Some embodiments further include identifying the subject as including a deficiency of the neurotransmitter if there is a statistically measurable difference between the reward modulation of the subject and a reference reward modulation and/or if the non-reward and the reward saccade movement parameters are statistically equivalent.Type: GrantFiled: June 2, 2014Date of Patent: February 28, 2023Assignee: University of Mississippi Medical CenterInventor: Lewis Chen

Patent number: 10404588Abstract: Techniques are described herein for optimizing communications in a network. At a router in a virtual private network, a packet is received from a device in a subnetwork protected by the router. The router examines the packet to determine a source address that identifies the device and a destination address that identifies a destination network device for the packet. The router also analyzes the packet to determine a size of the packet and determines whether or not the size of the packet is larger than a maximum transmission unit size. If the size of the packet is larger than the maximum transmission unit size, the router encapsulates the packet with a header that includes the destination address and a new source address that identifies the router.Type: GrantFiled: September 7, 2016Date of Patent: September 3, 2019Assignee: Cisco Technology, Inc.Inventors: Thamilarasu Kandasamy, Scott Fluhrer, Lewis Chen, Brian Weis

Patent number: 9832175Abstract: Techniques are presented for optimizing secure communications in a network. As disclosed herein, a key server is configured to provision a plurality of routers that are part of a virtual private network. The key server selects a counter value that is part of a security association and calculates a key value. The key server sends the key value, together with the security association, to the plurality of routers that are part of the virtual private network to enable them to exchange encrypted packets with each other in the virtual private network using the key value and the security association. The key server then increments the counter value to a value within a range of counter values capable of being predicted by the plurality of routers that received the key value.Type: GrantFiled: August 8, 2016Date of Patent: November 28, 2017Assignee: Cisco Technology, Inc.Inventors: Lewis Chen, Scott Fluhrer, Warren Scott Wainner, Brian Weis

Patent number: 9571459Abstract: Techniques are presented herein for optimizing secure communications in a network. A router in a virtual private network determines whether or not it has successfully registered with a key server that provides cryptographic keys for routers in the virtual private network. The router stores state information that is indicative of whether or not the router has successfully registered with the key server.Type: GrantFiled: April 20, 2016Date of Patent: February 14, 2017Assignee: Cisco Technology, Inc.Inventors: Lewis Chen, Warren Scott Wainner, Guan Deng

Patent number: 9444796Abstract: Techniques are presented for optimizing secure communications in a network. A first router receives from a second router an encrypted packet with an unknown security association. The first router examines the packet to determine whether the counter value is in a range of predicted counter values. Additionally, a key server is configured to provision routers that are part of a virtual private network. The key server selects a counter value that is part of a security association and calculates a key value. The key server sends the key value together with the security association to enable routers to exchange encrypted packets with each other in the virtual private network using the key value and the security association. The key server increments the counter value to a value within a range of counter values capable of being predicted by the routers.Type: GrantFiled: April 9, 2014Date of Patent: September 13, 2016Assignee: Cisco Technology, Inc.Inventors: Lewis Chen, Scott Fluhrer, Warren Scott Wainner, Brian Weis
