Examples of increasing yield and operating temperature range of transmitters are disclosed. In one example, a transmitter has an a thin-film bulk acoustic (FBAR) resonator. The transmitter may be a Bluetooth Low Energy (BLE) transmitter. In this example, the FBAR-based BLE transmitter does not require or have a phase locked loop, and does not require or have a crystal reference. The FBAR-based BLE transmitter may have an oscillator with a split capacitor array. The oscillator may be a Pierce oscillator with a split capacitor array. The FBAR-based transmitter and calibration methods described herein provide a greater yield and wider operating range than prior transmitters.

Increasing yield and operating temperature range of transmitters

Methods and systems for using unique identifiers to retrieve configuration data for tag devices are described herein. An example method may involve obtaining a unique identifier associated with a tag device. The tag device may include an antenna and a sensor configured to obtain sensor readings that can be wirelessly transmitted to a reader device via the antenna. The method may also involve determining configuration parameters associated with the tag device based on the unique identifier. The method may further involve storing, in at least one memory, at least a portion of the configuration parameters in association with the unique identifier.

Using unique identifiers to retrieve configuration data for tag devices

An example device includes a silicon substrate having a first substrate surface and a second substrate surface; a plurality of layers associated with one or more electronic components of an integrated circuit (IC), where the plurality of layers are deposited on the second substrate surface; a lithium-based battery having a plurality of battery layers deposited on the first substrate surface of the silicon substrate, where the lithium-based battery includes an anode current collector and a cathode current collector; a first through-silicon via (TSV) passing through the silicon substrate and providing an electrical connection between the anode current collector and the plurality of layers associated with the one or more electronic components of the IC; and a second TSV passing through the silicon substrate and providing an electrical connection between the cathode current collector and the plurality of layers associated with the one or more electronic components of the IC.

Body-mountable device with a common substrate for electronics and battery

In one aspect of the present disclosure, a method is disclosed. The method involves: a reader detecting an eye-mountable device within a wireless communication range of the reader, wherein the eye-mountable device includes a transparent material having a concave mounting surface configured to be removably mounted on a corneal surface; wirelessly retrieving from the detected eye-mountable device a first set of data; using the retrieved first set of data to determine that a condition has been satisfied; and responsive to using the retrieved first set of data to determine that the condition has been satisfied, retrieving from the detected eye-mountable device a second set of data.

Conditional retrieval

In one aspect of the present disclosure, a method involves obtaining, by a body-mountable device, sensor data, where the body-mountable device includes a data storage. The method further involves making a determination that each condition in a condition set has been satisfied. In addition, the method involves responsive to making the determination that each condition in the condition set has been satisfied, storing the obtained sensor data in the data storage.

Conditional storage

The present disclosure relates to a method that includes calculating a first frequency drift associated with an oscillator at a current temperature; based on the calculation, generating a first signal indicative of temperature compensation data; generating a second signal indicative of packet data and a modulation scheme; using the first signal, the second signal, and a first predetermined signal to generate a first tuning signal; and using the first tuning signal to tune a first capacitor array coupled to the oscillator and a second tuning signal to tune a second capacitor array coupled to the oscillator such that (i) the oscillator generates a modulated RF signal indicative of the packet data and (ii) the modulated RF signal has a second frequency drift that is less than a threshold.

Temperature-stable FBAR transmitter

Systems and methods are described that relate to a device, such as an eye-mountable device. The eye-mountable device may include a capacitance sensor and associated circuitry configured to measure a capacitance and/or a change in capacitance based on a material being in proximity with the capacitance sensor. For example, the capacitance sensor and associated circuitry may be operable to detect an eye-related movement of a wearer of the eye-mountable device. The eye-related movement may be a blink, a wink, an eye moving with respect to an eyelid, an eyelid moving with respect to the capacitance sensor, or an eyelid closing. At least one sensor electrode of the capacitance sensor may operable to carry out an additional function, e.g. to measure a level of glucose in tear-fluid or to provide wireless communication.

Capacitive sensing using a contact lens sensor

Example radio frequency (RF) transmitters and associated methods are disclosed. One example RF transmitter includes an RF oscillator, a real-time clock (RTC) oscillator. and a control circuit. The control circuit is configured to determine whether a calibration of the RF oscillator is needed; electrically couple the RF oscillator to the RTC oscillator and initiate calibrating of the RF oscillator using the RTC oscillator when it is determined that the calibration is needed; and activate the RF oscillator to operate in an open-loop mode to generate an RF signal for data transmission. The calibration can be performed in a closed-loop mode before the data transmission or in an open-loop mode during the data transmission.
