Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: A firmware massive update method using a flash memory includes: a firmware data registration step of receiving, from a manufacturer server, at least one of information of a user device that is a firmware update target, and firmware information and registering the received information as firmware data; a firmware data management step of receiving a request from a firmware update server in which the registered firmware data is stored, and storing and managing the registered firmware data in a specific area of a flash memory included in the user device via a network; and a firmware update execution step of executing a firmware update on the firmware data managed in the specific area of the flash memory included in the user device through the firmware update server.

Abstract: A firmware update shared key management method using a flash memory includes: a firmware data registration step of receiving, from a manufacturer server, at least one of information of a user device that is a firmware update target, and firmware information and registering the received information as firmware data; a firmware data management step of receiving a request from a firmware update server in which the registered firmware data is stored, and storing and managing the registered firmware data in a specific area of a flash memory included in the user device via a network; a shared key verification execution step of using a shared key to execute verification on a command communicating between the user device including the flash memory and the firmware update server that performs firmware update; and a firmware update execution step of performing firmware update of the user device through the firmware update server only when the encrypted command and the shared key pass the verification.

Abstract: A multipath searching device includes a radio front-end for converting a received radio signal into a baseband signal and for outputting the baseband signal. A profile calculating unit is included for calculating and outputting the multipath profile of the baseband signal. A first detector determines whether or not the radio signal traveled along a multipath is having a short-delay path by comparing the peak value of the multipath profile with a profile value of a predetermined position time interval before or after the peak of the multipath profile. A path selector receives the multipath profile and the detection result of the first detector, generates time delay information for each path, and separates many paths along which the radio signal traveled. A receiving unit receives the time delay information of the paths, despreads the baseband signal, and combines despread signals.

Abstract: The invention relates to a device and a method for the detection, especially on line detection, of an amplification of a DNA and/or RNA sequence in a sample. The amplification of the DNA and/or RNA sequence in the sample is evaluated on the basis of scattered-light signal of the sample.
