Patent number: 12581583Abstract: Devices, systems, methods, and processes for operating illumination devices on network devices are described herein. Illumination devices, such as light-emitting diodes, on network devices can provide useful status information when being observed by a technician. However, these illumination devices are often not being looked at in large data centers. As such, energy is often wasted on powering these illumination devices. In order to avoid this wasted power usage and increase sustainability, various embodiments described herein turn off illumination devices, such as network indicator lights and overhead lights, as a default state and illuminates them in response to a specific need. This need can be in response to a work order as well as to illuminate a path form an access point of the server room to the target network device that requires work by the network technician. Dynamically engaging illumination devices associated with network devices can reduce overall power usage.Type: GrantFiled: December 5, 2023Date of Patent: March 17, 2026Assignee: Cisco Technology, Inc.Inventors: Valentin Filippov, Elena Gribanova, Jenita John, David C.

Patent number: 12542827Abstract: Techniques for peer-to-peer backup in an administrative domain are described. The techniques may include identifying, by a first device, a second device as a trusted peer device. The techniques may also include receiving an advertisement that the second device supports a peer-to-peer backup system and transmitting an acknowledgement to the second device that the first device supports the peer-to-peer backup system. Additionally, techniques may include receiving a request to store backup data associated with the second device on the first device, the request may include an amount of memory needed. If the first device has the needed memory, the first device may transmit an indication that the memory is available. The indication may include a recovery key. The first device may then receive backup data associated with the second device, encrypted with the recovery key, and store the encrypted backup data in memory reserved for peer-to-peer backup data.Type: GrantFiled: April 18, 2023Date of Patent: February 3, 2026Assignee: Cisco Technology, Inc.Inventors: Jay Kemper Johnston, Magnus Mortensen, David C.

Patent number: 12519761Abstract: This disclosure describes techniques for data path monitoring and visibility in communications among network devices. The techniques include determining that personally identifiable information (PII) is included in a data traffic flow intended for delivery to a destination endpoint. A probe may be sent from a source endpoint to identify an intended data path of the data traffic flow to the destination endpoint. The techniques include validating the intended data path of the data traffic flow against a policy related to data routing. Based at least in part on a result of the validation, the techniques may include allowing or dropping the data traffic flow, or various other actions.Type: GrantFiled: August 25, 2022Date of Patent: January 6, 2026Assignee: Cisco Technology, Inc.Inventors: Ana Andrijic, Srilatha Vemula, David C. White, Arati Shimikeri, Poorna Rajaraman

Publication number: 20200074862Abstract: In one embodiment, a first vehicle makes, using a first machine learning-based model, a determination that raw image data captured by the first vehicle does not indicate the presence of a driving hazard. The first vehicle sends a hazard assessment request to a second vehicle in communication proximity of the first vehicle that includes the raw image data. The first vehicle receives a hazard detection response from the second vehicle that indicates a driving hazard identified by the second vehicle by applying a second machine learning-based model to the raw image data included in the hazard assessment request. The first vehicle adjusts a path of travel of the first vehicle to avoid the driving hazard identified by the second vehicle.Type: ApplicationFiled: August 30, 2018Publication date: March 5, 2020Inventors: Jay Kemper Johnston, David C.

Publication number: 20170022857Abstract: A decompression assembly (12) and method can include a linkage mechanism (20), a biasing assembly (38) for normally biasing the linkage mechanism toward a locked position when an internal combustion engine (10) is in an unpowered state, and an actuating piston (44) for driving the linkage mechanism from the locked position toward the unlocked position when the engine (10) is in a powered state. The engine can include a cam lobe (70) for driving pivotal oscillation of a rocker arm (36) engageable with a valve (16) in the engine for movement between open and closed positions. The linkage mechanism allows a full range of movement of the rocker arm when in an unlocked position, and restricts movement of the rocker arm to less than a full range of movement when the linkage mechanism is in a locked position for maintaining the valve in a partially open position.Type: ApplicationFiled: March 25, 2015Publication date: January 26, 2017Inventors: Matthew E.

Patent number: 9366159Abstract: A variable cam timing assembly (10) and method for an internal combustion engine of a motor vehicle includes a cam phaser (22) connected between an inner camshaft (12a) and an outer camshaft (12b) of a concentric camshaft (12). A torsional drive mechanism (14) connects between the cam phaser (22) and the inner camshaft (12a) for transmitting rotational torque. The torsional drive mechanism (14) permits adjustment for perpendicularity and axial misalignment of the inner and outer camshafts (12a, 12b), while maintaining a torsionally stiff coupling between the cam phaser (22) and one of the inner and outer camshafts (12a, 12b) of the concentric camshaft (12). The torsional drive mechanism (14) can be formed from one of a flexible shaft coupling (40), a transversely split driven gear (140), a transversely split sprocket ring gear (240), a transverse face spline gear (340), and a pin and slot combination drive (440).Type: GrantFiled: March 14, 2012Date of Patent: June 14, 2016Assignee: BorgWarner, Inc.Inventors: Mark Wigsten, David C.
