A circuit component may determine whether first signal indicative of at least one of the plurality of communication interface circuits accessing the FEM during a respective communication slot associated with the FEM has been received, determine a first Received Signal Strength Indicator (RSSI) value for the respective communication slot used by the FEM based on data associated with the respective communication slot, and store the first RSSI value in response to the first signal not being received. The circuit component may then determine a first gain for a subsequent slot based on the first RSSI value and discard the first RSSI value in response to the first signal being received.

A system and method for monitoring a walking activity are disclosed, which have three major components: a pre-processing phase, a step detection phase, and a filtering and post-processing phase. In the preprocessing phase, recorded motion data is received, reoriented with respect to gravity, and low-pass filtered. Next, in the step detection phase, walking step candidates are detected from vertical acceleration peaks and valleys resulting from heel strikes. Finally, in the filtering and post-processing phase, false positive steps are filtered out using a composite of criteria, including time, similarity, and horizontal motion variation. The method 200 is advantageously able to detect most walking activities with accurate time boundaries, while maintaining very low false positive rate.

A tethered phone case and holder assembly for convenient carrying and damage prevention includes a pouch apparatus, a case apparatus, and a tether apparatus. The pouch apparatus comprises a pouch body defining a pouch interior and a clip coupled to a pouch back side to selectively engage a user's belt or waistline. The case apparatus comprises a case body defining a case interior. The case body is selectively engageable within the pouch interior. The case interior selectively receives a smartphone. A cable attachment is coupled to the case body. The tether apparatus comprises a cable compartment coupled to the pouch body. A tether cable is coupled to a cable spool within the cable compartment and extends out to couple with the cable attachment of the case apparatus.

Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system communicatively couples to portable radios that operate on different RF frequencies via a communications hub. Some of the antennas elements are dynamically positionable (i.e., swappable, switchable, etc.) on the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end. The demountable fasteners couple to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements are formed using a conductive composition of fully exfoliated graphene sheets present as a percolated network in a polymer matrix.

This Application describes efficient cellular service transfer mechanisms to move cellular services that are based on cellular service credentials, e.g., eSIMs, between accessory wireless devices under various scenarios, including in some embodiments transfer of multiple eSIMs. The first and second accessory wireless devices and the primary wireless device are associated with a common user account. Transfer of credentials for cellular service access can occur between two accessory wireless devices via the primary wireless device, where the primary wireless device and the accessory wireless devices interact with applicable network-based servers.

A monitoring and alerting system can be used in any condition with a respiration component. Respiratory symptoms as well as supporting physiological functions are tracked against the user's baseline and alerts the user when there is a worsening trend. The system is self-contained in a wearable that detects and logs the signals, analyzes them and generates alerts. The wearable is untethered during use and may be attached to the body in various manners, such as with adhesives, clothing, clips, belts, chains, necklaces, ear pieces, clothing circuits or the like. Information can further be transmitted both wirelessly and via wire to devices, cloud storage, or the like.
