Abstract: A solar cell, a textured surface structure and a method for preparing the same are provided. The textured surface structure is formed on a surface of a silicon wafer, and the surface has a grid line covered area and a light-receiving exposure area. The textured surface structure includes a first textured surface formed on the grid line covered area, and a second textured surface formed on the light-receiving exposure area. The texture size of the first textured surface is larger than the texture size of the second textured surface.

Abstract: Embodiments include apparatuses, systems, and methods associated with modulating a clock signal to encode information. A system may include a plurality of dies including a first die. The first die may include a real time clock (RTC) circuit to receive clock information associated with a shared clock signal that is shared among the plurality of dies, and modulate a RTC signal to encode the clock information. The first die may further include an output terminal coupled to the RTC circuit to pass the modulated RTC signal to one or more other dies of the plurality of dies. A second die of the plurality of dies may include a decoder to receive the modulated RTC signal and extract the clock information. The second die may adjust and/or condition the shared clock signal based on the received clock information. Other embodiments may be described and claimed.

Abstract: A shutoff device includes a guiding unit, a bread carriage connected movably to the guiding unit, a lever unit, and a switch. The bread carriage includes a first carriage body. The lever unit has a contact segment that has a lower portion disposed between first and second portions of the first carriage body, and an upper portion disposed above the lower portion and the first portion of the first carriage body. The lever unit is upwardly movable relative to the bread carriage, with the lower portion being moved toward the first portion of the first carriage body and the upper portion being moved away from the first portion of the first carriage body, thereby converting a contact portion of the switch from a contact position to a shutoff position.

Abstract: A method for determining an image rejection characteristic of a receiver within a transceiver is provided. The transceiver uses a common local oscillator. The method includes generating a test signal having a spectral peak and generating a local oscillator signal comprising a frequency with an offset from a center frequency of the spectral peak. Further, the method includes down-mixing the test signal in the receiver using the local oscillator signal to generate a down-mixed signal. The method further includes calculating a first value of a signal characteristic of the down-mixed signal in a first frequency range corresponding to a desired signal component of the down-mixed signal and calculating a second value of the signal characteristic of the down-mixed signal in a second frequency range corresponding to an undesired signal component of the down-mixed signal. Further, the method includes comparing the first value and the second value to generate the image rejection characteristic.
