| 20100030429 | STEERING OPERATION FORCE DETECTING APPARATUS - A steering operation force detecting apparatus enabling to know in detail a force or a moment applied to a steering wheel rim (steering wheel) gripped by a driver during steering is provided. A force and a moment applied to each divided portion | 02-04-2010 |
| 20100049278 | METHOD OF SELECTING SPECIFIC SKELETAL MUSCLE HIGHLY SENSITIVE TO HUMAN PSYCHOLOGICAL STATE, DEVICE FOR SELECTING SPECIFIC SKELETAL MUSCLE, METHOD OF EVALUATING STRESS DURING WORK, AND SYSTEM FOR EVALUATING STRESS DURING WORK - The selecting method and apparatus for selecting a specific skeletal muscle affected by a psychological state of a person from skeletal muscles of the person apply at least a first stimulus to the person to bring the person into an uncomfortable state, acquire muscle activity information of each of the skeletal muscles when the first stimulus is applied to the person and select the specific skeletal muscle based on the muscle activity information of each of the skeletal muscles by the first stimulus. The stress evaluating method and system acquire the muscle activity information of the person during an operation for the selected specific skeletal muscle selected by the selecting method and apparatus, and evaluate a degree of stress placed on the person during the operation based on the acquired muscle activity information. | 02-25-2010 |
| 20100179764 | METHOD, APPARATUS, AND PROGRAM FOR EVALUATING DRIVABILITY OF A VEHICLE - A time series myoelectric potential signal is acquired, which is representative of time series activity amount of a muscle of a driver when the driver is performing a driving operation on the vehicle, the muscle being involved in the driving operation. Based on the acquired time series myoelectric potential signal, a parameter value indicative of a fluctuation amount of the time-series myoelectric potential signal and an average value of the myoelectric potential signal are obtained. Drivability of the vehicle is evaluated based on the obtained parameter value and the obtained average value. | 07-15-2010 |
| 20110112770 | VEHICLE EVALUATION METHOD AND VEHICLE EVALUATION APPARATUS - The vehicle evaluation method and vehicle evaluation apparatus can appropriately and quantitatively evaluate the sense of lateral oscillation of a vehicle. The method and apparatus measure muscle activity waveforms of a pair of left and right muscles in at least one type of skeletal muscle involved in maintaining a posture of a head of an occupant of the vehicle driven under predetermined driving conditions, calculate an amount of simultaneous activity that expresses characteristics of the muscle activity waveforms and evaluate a sense of lateral oscillation of the vehicle based on the amount of simultaneous activity. | 05-12-2011 |

| 20090012381 | Bioelectrical Information Acquisition Device And Inappropriately-Attached-Electrode Identifying Method - A plurality of electrode pairs, each of which is constituted by two electrodes of the plurality of biomedical electrodes are set and at least one of an electrical impedance value between two electrodes forming a pair and a resistance value between the two electrodes, for each of the electrode pairs is measured. An attachment state of each of the electrode pairs is judged by comparing the impedance value or the resistance value, with a predetermined range of numeric values. An electrode in an inappropriate attachment state is identified from the plurality of electrode pairs based on the judged attachment state o each of the plurality of electrode pairs. | 01-08-2009 |
| 20090287374 | METHOD AND SYSTEM FOR EVALUATING DRIVING CONDITIONS OF A VEHICLE - The method and system evaluate driving conditions of a vehicle whereby drivability of the vehicle can be evaluated accurately and objectively. To evaluate drivability of the vehicle under different driving conditions, a plural pieces of driving load information including biological information on a driver and movement information of the vehicle being driven are measured. Then, a group of weighting coefficients as many as or fewer than pieces of the driving load information is selected from groups of weighting coefficients that are set according to representative values of the driving load information in order to use a weighted linear sum of the representative values of the driving load information as an index of an integrated evaluation of the drivability of the vehicle. Subsequently, a weighted linear sum is obtained using the selected group of weighting coefficients and used to perform the integrated evaluation of the drivability under various driving conditions. | 11-19-2009 |
| 20100139395 | METHOD FOR EVALUATING AN INSTRUMENT OPERATING FORCE - Different loads are applied to the skeletal muscle of at least one of an upper arm, an upper limb girdle, and a lower limb of the test subject to cause isometric muscle contraction under each load and measure the muscle activity of the skeletal muscle. Then, an upper limit of the muscle activity in a region where a magnitude of the load and an intensity of the muscle activity have a linear relationship is determined as the limit in an appropriate muscle activity range that suits the test subject. Subsequently, the muscle activity of the skeletal muscle of a test subject operating an instrument is measured, and the test subject's force for operating the instrument is evaluated based on a frequency distribution where the frequency of the muscle activity of the skeletal muscle being exercised to operate the instrument is distributed with respect to the obtained limit. | 06-10-2010 |
