Patent number: 11964725Abstract: A control device of a bicycle includes an actuator and a first controller. The first controller is configured to generate and transmit, from the first controller to a second controller of the bicycle, messages for a predetermined time period at a first transmission rate in response to activation of the actuator. The first controller is further configured to, after the predetermined period of time, generate and transmit, from the first controller to the second controller, one or more messages at a second transmission rate until the actuator is deactivated. The first transmission rate is greater than the second transmission rate, and each of the messages includes data identifying the activation of the actuator.Type: GrantFiled: August 31, 2021Date of Patent: April 23, 2024Assignee: SRAM, LLCInventors: Sage Hahn, Kristi Lin, Alexander Kon-I Ho

Patent number: 11945533Abstract: An electrically actuated component of a bicycle includes a first controller configured to receive a data stream from a second controller. The data stream includes one or more packets received by the first controller. For each of the one or more packets received by the first controller, the first controller is configured to identify a number of the one or more packets of the data stream received by the first controller, and compare the identified number of packets to a predetermined threshold number of packets. After all packets of the one or more packets of the data stream have been received by the first controller, the first controller is configured to initiate, based on the respective comparison, an action of the electrically actuated component or another electrically actuated component of the bicycle when the identified number of packets is less than the predetermined threshold number of packets.Type: GrantFiled: July 12, 2021Date of Patent: April 2, 2024Assignee: SRAM, LLCInventor: Sage Hahn

Publication number: 20230415845Abstract: An electronic component for a bicycle includes a processor configured to receive first data from a first sensor configured to sense at least one sensed element disposed about a bicycle wheel as the sensed element rotates through a proximal region of the first sensor. The processor is further configured to receive second data from a second sensor. The second data is different than the first data. The processor is configured to determine a first speed based on a subset of the received first data when the sensed element is within the proximal region of the first sensor, and determine a second speed based on a subset of the received second data and the first speed when the sensed element is not within the proximal region of the first sensor.Type: ApplicationFiled: June 23, 2022Publication date: December 28, 2023Applicant: SRAM, LLCInventors: SAGE HAHN, SHELBY SESSIONS, SEBASTIAN HEYNA

Patent number: 11840315Abstract: In an adjustment mode for a derailleur of a bicycle, acceleration values from an accelerometer of the derailleur are sampled as the derailleur moves through sprockets of a rear sprocket assembly. Acceleration signal powers are identified based on the sampled acceleration values, and potential rasping positions are identified based on thresholding of the acceleration signal powers. The identified potential rasping positions are compared to expected rasping positions, and adjustment for the derailleur is set based on a minimum error between the identified potential rasping positions and the expected rasping positions.Type: GrantFiled: April 30, 2020Date of Patent: December 12, 2023Assignee: SRAM, LLCInventor: Sage Hahn
