MATLAB Coding and Examples of Nyquist Stability Criterion. The Nyquist criterion is widely used in electronics and control system engineering, as well as other fields, for designing and analyzing systems with feedback. While Nyquist is one of the most general stability tests, it is still restricted to linear, time-invariant (LTI) systems.

Some adult devices are ostensibly marketed to improve female sexual experience female by offering exercises to address relaxed vaginal muscles from birth, age, surgery etc. and for reducing incontinence. However, such devices suffer from variable placement by the user both in terms of orientation and penetrative depth such that the “results” are not reproducible and captured data used to provide feedback to the user and/or providing visual/audible prompts is flawed. Accordingly, it would be beneficial to provide a device with reproducible placement and data for enhancing the usability/benefit of the exercise regimen. It would be further beneficial for the device to either provide this exercise regime as part of a wider assessment of sexual wellness or as part of a sexual stimulation activity thereby reducing the focus on “exercise” to derive the benefits of improved pelvic muscle control.

The computer full-automatic sperm-collecting and penis erection monitoring analysis system includes sperm-taking device, controller instrument, display screen and printing machine, acoustic horn and electric pulse output electrode. Said sperm-taking device has a shell body with hole in which a sliding cover is set. Said sperm-taking device can adopt acoustic, optical, electric, magnetic and thermal multiple organoleptic all-bearing stimulation and adds the functions of gripping, circularly-pressing, vibration and magnetotherapy to simulate female vaginal environment in venered excitatory state.

A male masturbation device and method for using same facilitates orgasm without the necessity of the subject achieving an erection. The novel device comprises a housing and accumulator means. The accumulator means maintains a consistent modest vacuum within the housing notwithstanding sliding of the penis within the housing. The accumulator means can be integrated with the housing or detached from but in fluid communication with the housing. The device may be used with or without a partner and its use may be augmented by sensory stimulation contrivances. The novel device and method offers the health and recreational benefits of orgasm, and facilitates semen collection, for individuals suffering ED, without resort to drugs or vacuum erection devices.The novel device takes advantage of the fact that an erection is not required for orgasm, however, users may experience an erection prior to ejaculation.

The invention belongs to the technical field of medical instruments, and particularly relates to a miniature multi-sensing technology based multi-parameter dynamic monitoring and recording device for penile erection states. The device is medical auxiliary monitoring equipment which combines a dynamic penile erection state sensing monitoring technology and a continuous data recording method and dynamically monitors change of multiple indexes such as biological impedance, penile position angles, axial penile pressure, penile blood flow and the like in the penile erection states. The monitor comprises a physiological parameter acquisition module, an embedded master control module as well as accessories such as a lead, a battery, an elastic fiber sleeve and the like. All the function modules coordinate with one another to work under the unified control of the master control module and acquire, process and record physiological information capable of reflecting various function states in penises of monitored patients in real time. The device can realize non-invasive, reliable and continuous monitoring of the penile erection states of the patients in real and natural sleep states and provide powerful and objective data reference for clinical assessment of male erectile dysfunctions.
