Abstract: A method of varying the appropriate muscle strength of a person to at least alleviate urinary of fecal urgency or incontinence, or vaginal or bladder spasms, includes placing a surface electrode of electromyographic measuring apparatus at an appropriate position on the person and/or inserting a probe electrode of electromyographic measuring apparatus and or pressure transducer probe of pressure measuring apparatus into the vaginal or arlal passage of a person and measuring with the electromyographic or pressure measuring apparatus the appropriate muscle strength of the person while the person is tensing the approrpiate muscles in a urine or feces stopping manner to obtain an EMG or pressure signal. The threshold value of a portable electromyographic or pressure measuring unit is then adjusted to enable the person to repeat the measurement at different times to attempt to obtain better EMG or pressure signals in an urge, incontinence or spasm reducing sense. The portable unit gives an audible and/or visual and/or tactile indication when an EMG or pressure sinal representating an improvement relative to the threshold value is achieved.

Title: Log splitting device
Inventor: COUTU CHRISTIAN
IPC: B26D7/26
Filed: 1995-07-18
Abstract: A splitting device for splitting logs of wood. The device includes an elongated chassis. A guiding rail is mounted on the chassis. A conveyer having a set of endless segmented members is also mounted on the chassis. Each endless segmented member has a pushing component adapted to push the logs along the guiding rail towards the front end of the chassis. The pushing components are adapted to contact the guiding rail adjacent its rear end and to disengage from the guiding rail adjacent its front end. A stopper component is provided adjacent each pushing component for preventing a pivotal movement of the pushing component relatively to the endless segmented member when the pushing component contacts the guiding rail, while allowing the pivotal movement of the pushing component when the latter disengages from the guiding rail. A blade is fixed to the chassis adjacent its front end. The blade has a frontal cutting edge. The blade is positioned in a frontwardly spaced relationship relatively to the guiding rail front end. The pushing components are adapted to push the log against the blade, thus causing the latter to split.
