摘要:
The application relates to a stimulation device with power conservation functionality. In implantable devices, power supplies may be limited. Replenishing these power supplies may require costly surgery or periodic recharging depending on the model. A method may be implemented that skips or drops periodic pulses without apparently changing the frequency of the pulses. In this manner, the dropped pulses may be undetected by the patient. On the other hand, the dropped pulse represents power savings. Dropping one in ten pulses may lead to a 10% energy savings. The stimulation device may implement the method with one or more counters implemented in hardware or software.

An implantable, substantially isodiametric, low resistance implantable lead having at least one electrode positioned in a stimulation/sensing portion of the lead as well as a method of manufacturing the same. At least the stimulation/sensing portion is unitized through partially surrounding and supporting insulation and conductive element(s) of the stimulation/sensing portion with a fused matrix of material having mechanical properties consistent with a body of the lead.

Active-response golf shoes are disclosed. The golf shoes include at least one sensor, a controller, and at least one active-response element. The sensor and controller operate to rapidly determine if a golfer is walking or swinging a golf club. Once this determination is made the controller and active-response element rapidly change the shoe's characteristics. If the controller determines that the golfer is walking, the shoe provides a soft and flexible walking platform. If the controller determines that the golfer is swinging, the shoe morphs or changes automatically to provide a stable hitting platform. The controller senses various predetermined conditions such as pressure under the ball of the user's foot to determine whether the golfer is walking or swinging. The active-response elements may be a sole adjuster, a lace adjuster, and/or an upper adjuster. Methods of determining the golfer's type of movement are also disclosed.

The invention provides compositions and methods that are useful for preventing and treating a coronavirus infection in a subject. More specifically, the invention provides peptides and conjugates and pharmaceutical compositions containing those peptides and conjugates that block fusion of a coronavirus, such as the SARS virus, to a target cell. This blocking mechanism prevents or treats a coronavirus infection, such as a SARS infection, in a subject, such as a human subject.

In one embodiment, a method electrically stimulates an area in a spinal disc. The method comprises: implanting at least one steerable lead at a placement site for stimulating a spinal disc such that the lead is disposed exterior and immediately adjacent to and circumferentially along an annulus of the spinal disc, the at least one lead including a plurality of electrodes distributed along a majority of a circumference of the annulus; connecting the lead to a signal generator; and generating electrical stimulation pulses using the generator to stimulate targeted portions of the spinal disc, wherein the stimulation of the targeted portion of the spinal disc sufficiently stimulates nerve tissue within the spinal disc to prevent communication of pain signals originating in the spinal disc without damaging tissue of the spinal disc.

A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.

An electronic controller for a vehicle leveling system comprises an extend-enable switch, a retract-enable switch, an all-activate switch, and at least one group-activate switch. It is configured to generate an all-extend electronic signal upon coordinated actuation of the extend-enable switch and the all-activate switch, an all-retract electronic signal upon coordinated actuation of the retract-enable switch and the all-activate switch, a group-extend electronic signal upon coordinated actuation of the extend-enable switch and the group-activate switch, and a group-retract electronic signal upon coordinated actuation of the retract-enable switch and the group-activate switch. Vehicle leveling systems having the electronic controller further include a plurality of jacks operably controlled by the electronic controller and a power system.

A system for and method of evaluating a log. The system includes an analysis module having at least one input terminal connectable to the at least one input device. The at least one input terminal is operable to receive at least one signal representing at least one measured property of the log and at least one determined parameter of the log determined in response to an energy being applied to the log. The analysis module further includes a processor coupled to the at least one input terminal. The processor determines a predictive modulus of elasticity (MOE) of the log based at least in part on the at least one measured property and the at least one sensed parameter. The analysis module also includes an output terminal coupled to the processor and connectable to an output device. The output terminal transmits a third signal representing the predictive MOE.
