An assembled record player includes: a box having a cover and a base, and the cover being covered onto the base, and a accommodating space being included between the cover and the base; a record player contained in the accommodating space; at least one loudspeaker and contained in the accommodating space; and a circuit board contained in the accommodating space. The cover and the base are separated, and an accommodating hole is formed on the cover, and the record player is installed and fixed to the accommodating hole, and the loudspeaker and the circuit board are fixed to the base, and the circuit board is electrically connected to the record player and the loudspeaker, and the cover of the record player is covered onto the base to form the record player. Therefore, users can experience the fun of assembling the record player.

A record player includes a base, a platter, a tonearm assembly and a monitoring unit. The monitoring unit is secured on the base, and includes a light emitter, an image capturing module and a processing module. The light emitter can emit light toward the platter or an acoustical record disposed on the platter. The image capturing module can receive the light reflected by the platter or the acoustical record, and capture images of the platter or the acoustical record. The processing module can receive the images from the image capturing module, and determine a current rotating speed of the platter or the acoustical record by analyzing and comparing the images captured by the image capturing module at successive time points.

A memory device including at least one channel and a fluid including particles is provided. In one aspect, the channel includes a least some of the fluid. The memory device may further include an actuator configured to induce a movement of the particles in the channel; and a writing element configured to arrange the particles in a sequence, thereby yielding a sequence of particles in the channel. The particles may include first particles and second particles. The particles may be in a first state or a second state in the channel. In certain aspects, the channel is configured to preserve the sequence of the particles. The memory device may further include a reading element for detecting the sequence of the particles in the channel.

A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area. The second region micropattern has a second sheet resistance value in the first direction. The first sheet resistance value is different from the second sheet resistance value.

A phono-preamplifier for processing audio output signals from a turntable is powered by a variable voltage adapter such as a USB-C PD power supply adapter.

A method of tracking record player stylus elapsed play time for quality and maintenance utilizes stylus playtime chronograph. The stylus playtime chronograph includes an internal memory that stores elapsed time of an associated stylus, wherein memory of the elapsed time will be maintained on the chronograph even if power supply is interrupted; a display that will display hour truncated elapsed time of an associated stylus; a start button to start and restart the recording of elapsed time of an associated stylus; a stop button to stop or pause the recording of elapsed time of an associated stylus; and a reset button to allow for resetting of the chronograph and allow the chronograph to be used for the another stylus.

Systems and methods for generating alerts based on potential health conflicts are described. The described systems and methods may provide for identifying unstructured text from a physical environment, performing natural language processing on the unstructured text to produce annotated text, comparing the annotated text to patient medical information to find a potential conflict, and generating an alert based on the potential conflict.

Methods, system and devices for the production of audio records are provided. A record format is selected, and this selection is used to modify a set of digital audio files. A music production interface may be provided to receive the selection. A set of manufacturing instructions are generated, which are derived from the modified set of digital audio files. The set of manufacturing instructions are used to convert a record blank into a playable audio record.
