The audio input provides a soothing noise such as a beating sound, the frequency of which may be adjusted, for example, 30 to 120 beats per minute. A voice synthesizer may speak directions to the user such as, for example, instructing the user to breathe in and out at a certain rate. A timer and speed control permit ready adjustment of the frequency of beats as well as the frequency during which voice synthesizer messages are provided. A microphone and tape recorder allow the user to tape record their own stress reducing instructions.

Abstract: The method enables individuals to monitor their state based on a five-point stress-reward scale, use the intrapsychic tool that corresponds with that state and continue that process of monitoring, identifying and using until they attain the state of lowest stress and greatest reward or until they accept the other state they are in. That acceptance can trigger them to attain the state of lowest stress and greatest reward. They do this 10 or more times per day. The process triggers immediate improvements in emotional and behavioral regulation that are short lived as this regulation is affected by neural circuitry. The intensive use of the system over time changes the neural circuitry so that attaining the state of lowest stress and greatest reward occurs spontaneously, more frequently and more easily. This brain retraining supports long-term improvements in emotional and behavioral regulation, and ultimately, health and happiness.

Abstract: Techniques for controlling delivery of a therapy to a patient by a medical device, such as an implantable medical device (IMD), involve a sensitivity analysis of a performance metric. The performance metric may relate to efficacy or side effects of the therapy. For example, the performance metric may comprise a sleep quality metric, an activity level metric, a movement disorder metric for patients with Parkinson's disease, or the like. The sensitivity analysis identifies values of therapy parameters that defines a substantially maximum or minimum value of the performance metric. The identified therapy parameters are a baseline therapy parameter set, and a medical device may control delivery of the therapy based on the baseline therapy parameter set.

Abstract: Images that can have various subjects are formed by using the specific range of colors that the rainbow has. These images consist primarily of transparent, flexible, 3-D pictures which become even more beautiful when light is passed through them. Their size varies and they can be transferred from one surface to another, so they can be removed easily and leave the room exactly as it was before. They are accompanied: (a) by stories explaining the specific meanings of each color used in the picture and of each transfer from one color to the next; and (b) by other stimuli for the senses (audio-visual images, odors, tastes, etc. which try to give life to the theme of the image and give the viewer the sense that he or she is actually in the image). Their aim is to convert a negative space into a positive, and healing, one.
