摘要:
A camera that is mountable in a mobile communications device is disclosed. The camera allows the user of the device to precisely adjust the acute rotational angle of the camera with respect to the body of the device and maintains the adjusted angle of the camera until the user deliberately adjusts it again.

Disclosed herein are a method of generating a two-dimensional hole gas (2DHG) using a type-2 quantum well formed using semiconductors with different electron affinities or band gap, and a high-speed p-type semiconductor device using the 2DHG. To this end, the method includes providing a semiconductor substrate; growing a first semiconductor layer on the semiconductor substrate, growing a second semiconductor layer with a different electron affinity or band gap from the first semiconductor layer on the first semiconductor layer, and growing a third semiconductor layer with a different electron affinity or band gap from the second semiconductor layer, thereby forming a type-2 quantum well; and forming a p-type doping layer in the vicinity of the type-2 quantum well, thereby generating the 2DHG.

A write driver control circuit controls operations of a write driver, which amplifies and transmits data of a pair of global input/output lines to a pair of local input/output lines in a write operation. A single type latch section compares states of first and second data of the pair of global input/output lines differentially inputted in a first status and then outputs a first output signal to a first output node; compares states of the first and second data differentially inputted in a second status and then outputs a second output signal to a second output node; and continuously latches states of the first and second output nodes before a precharge operation starts. A precharge controller equalizes and precharges the first and second output nodes in the precharge operation. An output section outputs first and second driver signals and first and second latch signals to control the write driver.

A memory system includes: a controller configured to provide a hidden auto refresh command; and a memory configured to perform a refresh operation in response to the hidden auto refresh command. The controller and the memory communicate with each other so that each refresh address of the controller and the memory has the same value as each other.

An address counting circuit includes a counter configured to sequentially count from an initial address in response to a clock signal in order to output counted addresses. The address counting circuit also includes a code conversion unit that is configured to output converted addresses such that only one address bit of the converted addresses with respect to the previous converted addresses are toggled to output the converted addresses. The converted addresses output form the code conversion unit do not overlap with one another.

A system, medium, and method conducing a user's breathing, in which a sound generated during a user's exhale and/or an ambient temperature change occurring during the exhale is sensed to measure a respiratory waveform of the user. Respiratory information of the user may then be produced from the respiratory waveform, and when the respiratory information of the user is different from normal respiratory information of the user, breathing information according to the normal respiratory information may be provided to the user so the user can use the same to modify their breathing.
