Various arrangements for detecting an object using a passive infrared (PIR) sensor module of a sensor device. A PIR data stream may be received from the PIR sensor module indicative of measurements performed by the PIR sensor module. An indication may be received from a transceiver that identifies a beginning of the data transmission. A portion of the PIR data stream may be blanked in response to receiving the indication of the beginning of the data transmission, the portion of the PIR data stream corresponding to a defined time duration. A presence of an object may be determined using the PIR data stream, excluding the blanked portion.

Integrated antenna system and related component management

An antenna system includes a dielectrically-loaded loop element electromagnetically coupled to a planar element. The antenna system exhibits uniform, broadband radiation and reception patterns.

Antenna system

Compact portable wireless devices and antennas for compact portable wireless devices are provided. The compact portable wireless device may be part of a piece of sports equipment. A compact portable wireless device may include a transceiver module that is used in communicating with equipment such as a handheld electronic device. An antenna for a compact portable wireless device can have a relatively small size while exhibiting high efficiency. A planar ground structure for the antenna may be formed from a circuit board on which integrated circuits have been mounted. A curved inverted-F resonating element may be attached to the ground structure. A battery may be provided to power the compact portable wireless device. The battery may be used as a parasitic antenna element.

Antennas for compact portable wireless devices

Antennas are provided for portable electronic devices. A portable electronic device may have a port that receives a wireless communications adapter. The adapter may be used to provide wireless functionality for the portable electronic device. The adapter may contain a chip antenna that serves as an antenna resonating element. A printed circuit board within the adapter may contain conductor that has been patterned to form a ground plane for the antenna. The portable electronic device may have a conductive structure such as a housing portion. The conductive structure of the portable electronic device serves as a parasitic antenna element that improves antenna efficiency. The portable electronic device may be a handheld electronic device with music player functionality that communicates with a compact portable wireless device in a piece of sports equipment.

A cable may be provided having a noise-suppression ferrite loaded magnetic tape wrapped in a spiral. The cable may have a strengthening cord at its core. Signal wires such as data wires and power wires may surround the strengthening cord. The signal wires may have copper cores that are coated with polytetrafluoroethylene insulating coatings. A metallized polyester tape may be wrapped around the signal wires to reduce electromagnetic interference. A braided copper shield may be formed over the metallized polyester tape. The magnetic tape may be wrapped around the metal braid. One or both edges of the magnetic tape may have uncovered areas in which no magnetic material is present. The cable may have connectors its ends. The magnetic tape wrap may extend from one connector to the other.
