  • Patent number: 11970795
    Abstract: Methods of manufacturing multi-material fibers having one or more electrically-connectable devices disposed therein are described. In certain instances, the methods include the steps of: positioning the electrically-connectable device(s) within a corresponding pocket provided in a preform material; positioning a first electrical conductor longitudinally within a first conduit provided in the preform material; and drawing the multi-material fiber by causing the preform material to flow, such that the first electrical conductor extends within the multi-material fiber along a longitudinal axis thereof and makes an electrical contact with a first electrode located on each electrically-connectable device. A metallurgical bond may be formed between the first electrical conductor and the first electrode while drawing the multi-material fiber and/or, after drawing the multi-material fiber, the first electrical conductor may be located substantially along a neutral axis of the multi-material fiber.

  • Publication number: 20240065390
    Abstract: Bands for wearable devices include multiple band retainers used to maintain engagement between an assembly (e.g., a pair) of bands. Some band retainers may be permanently affixed with the band at a certain location of the band, while other band retainers can be removable. The removable band retainers can be moved to different locations of the band, thus allowing the band retainer to retain another band at different locations. As a result, the assembly of bands can be used with different users, and in particular, users with different wrist sizes. Moreover, using multiple band retainers can provide an engagement force between the bands to withstand higher-impact events, such as swimming and diving. Additionally, bands and band retainers may include one or more liquid-resistant and corrosion-resistant materials.

  • Patent number: 9999011
    Abstract: A wireless network device including, in the wireless network device, a Bluetooth device and a wireless local area network device. The Bluetooth device is configured to establish a network of Bluetooth client stations and output a synchronization signal prior to a start of Bluetooth data transmission between the Bluetooth device and the Bluetooth client stations. The synchronization signal indicates the start of the Bluetooth data transmission. The wireless local area network device is configured to establish a network of wireless local area network client stations, receive the synchronization signal from the Bluetooth device, and transmit, a predetermined time subsequent to receiving the synchronization signal, a beacon to the wireless local area network client stations. The beacon instructs the wireless local area network client stations when to begin wireless local area network data transmission.

  • Patent number: 9886543
    Abstract: A pattern of features of an integrated circuit is provided. A configuration of a pupil of an extreme ultraviolet wavelength radiation beam (also referred to as an illumination mode), is selected. The selected configuration is an asymmetric, single pole configuration. At least one disparity is determined between a simulated imaging using the selected configuration and a designed imaging for the pattern of features. A parameter (also referred to as a compensation parameter) is then modified to address the at least one disparity, wherein the parameter at least one a design feature, a mask feature, and a lithography process parameter. A substrate is then exposed to the pattern of features using the selected configuration and the modified parameter.

  • Patent number: 9014207
    Abstract: A system including a physical layer module and a control module. The physical layer module is configured to generate a first clear channel assessment for a first sub-channel of a communication channel and generate a second clear channel assessment for a second sub-channel of the communication channel. The first clear channel assessment indicates whether the first sub-channel is free or busy. The second clear channel assessment indicates whether the second sub-channel is free or busy. The control module is configured to, in response to the second sub-channel being busy, extend a duration of the second clear channel assessment by a predetermined period of time, and transmit data via (i) only the first sub-channel or (ii) both the first sub-channel and the second sub-channel based on (a) the first clear channel assessment, (b) the second clear channel assessment, and (c) the extended duration of the first clear channel assessment.
