摘要： Techniques for implementing and/or operating a radio frequency system, which includes a logic board that outputs an analog electrical signal indicative of data to be wirelessly transmitted from the radio frequency system and a remote head. The remote head includes an antenna that generates an electromagnetic wave to facilitate wirelessly transmitting the data, an antenna integrated circuit implemented using a first semiconductor manufacturing technique, in which the antenna integrated circuit amplifies the analog electrical signal to generate a first amplified analog electrical signal, and a remote front-end integrated circuit coupled between the antenna integrated circuit and the antenna. The remote front-end integrated circuit is implemented using a second semiconductor manufacturing technique different from the first semiconductor manufacturing technique and amplifies the first amplified analog electrical signal based on a target output power of the antenna to generate a second amplified analog electrical signal indicative of the data.

摘要： A device is provided that includes a persistent memory, a microcontroller and a power source configured to generate power in response to energy harvesting. The power is transferred to a power storage of the device such that when the power storage has an amount of power the microcontroller performs processing of a part of a task resulting in state data related to the task stored to the persistent memory in response to a first cycle of energy harvesting. In response to one or more additional cycles of energy harvesting, the device continues performance of the task by retrieving the state data for the part of the task from the persistent memory and resulting in assembly of a payload that comprises an update to software running on the device.

摘要： A batteryless device is provided. The batteryless device includes a logic processor, a power storage cell, a sensor, a persistent memory, a wireless logic and an antenna configured to harvest power in response to exposure to radio frequency (RF) energy. The harvested power is transferred to the power storage cell such that when the power storage cell has a threshold amount of power the logic processor is activated to start or resume execution of code associated with a task of sampling the sensor, processing sensor data from the sensor into an encrypted message, and transmitting the encrypted message. The batteryless device transmits one or more of said encrypted messages using said wireless logic to a local device proximate to a location of the batteryless device. The one or more encrypted messages providing information related a state of a package to which the batteryless device is attached. The local device is configured for sending data related to said one or more encrypted messages to a cloud server for processing metrics related to the location and said state of the package. The local device is one of a plurality of local devices that become proximate to the batteryless device when the package moves proximate to said plurality of local devices at different times. The metrics enable tracking over time of the package and said state of the package.
