摘要:
A touch system and an optical touch system with a power-saving mechanism are presented. The touch system includes a sensing module and a processing module electrically connected to the sensing module; the optical touch system includes an optical sensing module and a processing module electrically connected to the optical sensing module. The processing module modulates a working frequency and/or a working voltage of the processing module according to a touch point count on a touch region, a preset function of the processing module, and/or an imaging count detected by the optical sensing module, so as to decrease a power consumption of the processing module. An electronic device equipped with such system may not only dynamically adjust the working frequency and/or the working voltage of the processing module, but also can determine a working frequency and/or a working voltage satisfying a report rate through an input of the system.

A sensing system includes a frame having a first boundary, a second boundary, a third boundary and a fourth boundary and defining a sensing area therein, a light source module for providing light to the sensing area, a first image sensor, a second image sensor, a third image sensor and a mirror component. The first image sensor is disposed between two neighboring ends of the first and second boundaries. The second image sensor is disposed between two neighboring ends of the second and third boundaries. The third image sensor is disposed between two neighboring ends of the first and fourth boundaries. The mirror component is disposed at the fourth boundary. A locating method of the sensing system can determine a location of a pointer accurately and avoid a problem of a blind zone.

An image sensing module includes an image sensor and a sensing controller. The image sensor captures an image with a first frequency. The sensing controller determines whether the image sensor has detected an object according to the image. When the sensing controller determines that the image sensor has detected an object, the sensing controller switches the image sensor to capture the image with a second frequency for the image sensor to continuously detect the location of the object. By setting the first frequency higher than the second frequency, the image-sensing module detects the object in real time and the power consumption of the image-sensing module continuously detecting the location of the object is saved as well.
摘要:
A locating method for an optical touch device to calculate a position of a light blocking object is provided. The optical touch device includes a number of image detecting components. Each of the image detecting components includes a number of pixels arranged in a straight line. In the locating method, the pixels of each of the image detecting components are at least divided into a first group and a second group. When the first group detects a dark point caused by the light blocking object, the position of the dark point is calculated using a first calculating method. When the second group detects the dark point, the position of the dark point is calculated using a second calculating method. The locating method can determine the position of the light blocking object accurately. An optical touch device that is suitable for using the locating method is also provided.
摘要:
An apparatus, method, and computer readable medium thereof for simultaneously establishing links with a plurality of nodes in a wireless network are provided. A processing module determines whether a mesh network configuration message of the apparatus has space to packet an information element and determines whether to transmit a Neighbor Link Establishment information element to one of the nodes. If the mesh network configuration message has space to packet an information element and the Neighbor Link Establishment information element needs to be transmitted to one of the nodes, the Neighbor Link Establishment information element will be packeted into the mesh network configuration message. Finally, a transmission module transmits the mesh network configuration message to the nodes in order to solve the problem of increasing time during link establishment and avoid deadlock among the nodes when the apparatus of the prior art establishes links with the nodes simultaneously.

A connection node, a method, a computer program, and a computer readable medium thereof for recalculating a transmission opportunity when an apparatus requests to enter a wireless network are provided. A receiving module receives a mesh network entry message transmitted from the apparatus. A memory stores an identification of a sponsor node. A processing module determines whether an original neighboring node list comprises the identification. If no, the processing module updates the original neighboring node list according to the identification, and recalculates a transmission opportunity of a mesh network configuration message of the connection node. Finally, a transmission module transmits the mesh network configuration message according to the transmission opportunity in order to solve the problem that mesh network configuration messages of nodes collide with each other of the prior art.
