An IoT wireless power transfer sensor is provided, which includes a sensor circuit, a group of retrodirective searching antennas, a group of energy harvesting antennas and a communication antenna. The sensor circuit includes a switching unit, an energy converting unit, a power management unit and an energy converting and storage unit. The searching antennas are connected to the switching unit. When the switching unit is on, the searching antennas don't harvest the energy of an external device's scanning signal; they reflect the incident energy to the external device. The energy harvesting antenna is connected to the energy converting unit and receives the incident energy to charge the energy converting and storage unit. When the power storage level of the energy converting and storage unit reaches a first threshold value, the switching unit is consecutively switched between on and off to transmit a device information in back-scattered way to the external device.

Internet-of-things wireless power transfer sensor

A smart hub is provided, which includes a control circuit and an antenna array (the functions thereof include transmitting/receiving scanning signals and transmitting wireless power transfer signals). The antenna array is connected to the control circuit and transmits a scanning signal to scan within an effective scanning range thereof. When the antenna array receives the reflected signal of the scanning signal, the control circuit controls the antenna array to keep transmitting a wireless power transfer signal, within a predetermined time interval, in the direction of receiving the reflected signal, and simultaneously receives the device information from a sensor which may exist via the antenna array within the predetermined time interval. The device information is generated by the sensor by backscattering.

Smart hub

A speaker is provided. The speaker includes a supporting shell, at least one first speaker monomer and a waxy material. The supporting shell includes at least one first sound port. The first speaker monomer is installed at the first sound port. The outer surface of the supporting shell is covered by the waxy material. Wherein an average thickness of the waxy material is more than or equal to an average thickness of the supporting shell.

A location-based service method may include providing a data related to an indicator; configuring the indicator to point out the data is related to a location of a provider of the data if the data is related to the location of a provider of the data; and transmitting the data and the indicator to a server through a first communication equipment to store the data in the server for a user to transmit, through the first communication equipment or a second communication equipment located closely to the first communication equipment, a query to search the data related to the location of the provider of the data by searching the data stored in the server and find data related to the location of the provider of the data. The data is searched based on the indicator related to each of the plurality of data.

Method of providing location-based service in a communication system

A location-based service method may include receiving a plurality of data through a first communication equipment, wherein each of the plurality of data is related to an indicator, the indicator being configured to indicate if the data is related to the location of a provider of the data, receiving a query through the first communication equipment or a second communication equipment located closely to the first communication equipment, and searching the plurality of data to find data related to the location of the provider and also related to the query to form a search result related to the query.

A cell-sensing unit is applied to a memory device having a cell associated operably with a complementary pair of bit lines and a word line. The cell-sensing unit includes a current sense amplifier having a first input side adapted to be connected to the bit lines, and a first output side, and a voltage amplifier having a second input side connected to the first output side of the current sense amplifier, and a second output side. The current sense amplifier is capable of magnifying a difference between currents flowing through the bit lines during a read cycle of the cell, and generates a corresponding voltage difference at the first output side. The voltage difference is received by the voltage amplifier at the second input side, and has a magnitude sufficient to enable the voltage amplifier to generate an output signal at the second output side corresponding to data stored in the cell.
