Famous Patents
Felix Hoffmann, a German chemist, was searching for something to relieve his father's arthritis. In doing so, he "rediscovered" acetylsalicylic acid and in 1900, patented a stable process for developing it. Hence, we have aspirin.

| Application No. | Application Title | Issue Date |
| 20110316722 | Incremental Coder and Method for Determining a Value of Variation of Stable Positions of the Coder An incremental coder in which stable positions of the coder are defined by multiples of an increment of the coder. The coder computes a difference between a binary word obtained for a current stable position and a binary word obtained for a previous stable position, and... | 12/29/2011 |
| 20090278711 | Sensor Arrangement for the Precise Detection of Relative Movements Between An Encoder and A Sensor A sensor arrangement and a method for the precise detection of relative movements between an encoder and a sensor, including an encoder, which has an incremental scale having a plurality of scale subdivisions (λ), and a sensor which is magnetically coupled to the encod... | 11/12/2009 |
| 20090184848 | ROTARY ENCODER AND METHOD OF MANUFACTURING THE SAME A rotary encoder includes a case made of insulating resin, a rotatable operation shaft, a slidable brush fixed to the operation shaft, and a signal contact embedded in a surface of the case. The slidable brush has a contacting section sliding on a surface of the case on... | 07/23/2009 |
| 20080129549 | SYSTEM AND METHOD FOR ENCODER FAILURE DETECTION An encoder failure detector system and method for detecting failure of an encoder during time periods when a zero rotational speed is expected. For example, in one embodiment a test signal is applied during a period when a zero rotational speed is expected and a failure... | 06/05/2008 |
| 20070176798 | SEMICONDUCTOR DEVICE INCLUDING A HIGH VOLTAGE DEVICE Embodiments relate to a high voltage device, a semiconductor device including the same and a method of manufacturing the same. The high voltage device may include a semiconductor substrate provided with at least a high voltage device, an isolation layer formed at an are... | 08/02/2007 |
| 20050078015 | Encoding system An encoding system for determining position and position changes of a moving member has a sequence of encoder marks forming incremental patterns and at least one index pattern. Two subsequent incremental patterns are indicative of an incremental position-change of the m... | 04/14/2005 |
| 20050072016 | Position measuring device A position measuring device including a code having a first code element and a second code element arranged one behind the other in a measuring direction, wherein each of the first and second code elements includes a first partial area and a second partial area, which a... | 04/07/2005 |
| 20050068200 | Input method of encoder signals The present invention relates to an input method of encoder signals, and more particularly, to an input method of encoder signals which senses encoder signals by setting a predetermined signal sensing period at which the encoder signals to be input are sensed, and adjus... | 03/31/2005 |
| 20050035884 | Process for automatically generating several electrical pulses using numeric default values, in particular for simulating an incremental encoder The invention relates to a method for automatically generating several electrical pulses using numeric default values, in particular for simulating an incremental encoder for a sequential, digital counting of linear or angular displacement values using said pulses. The ... | 02/17/2005 |
