This is NOT A VALID MEDICAL DEVICE IN ANY KNOWN UNIVERSE, ACTUAL OR FICTIONAL!!!

Pseudo-Medical Monitor for Christmas Cheap Gift

In preparation for the expected Christmas Gift availability crisis, I present the Pseudo-Gift of the season. The time honored tradition of knockoff products hitting the market before Christmas is alive and well. What better than a multi-property knockoff device? Star Trek / Arduino / Medical knockoff device gift for everyone. This Pseudo-Medical Tricorder ripoff is the stocking stuffer for 2021.

Operation

This device offers several functions to the user. The device is intended to be held by the user for self-analysis.

Monitoring

Passive Mode
Example Description
This device provides several passive functions when not placed in specific function modes. The passive mode consists of a thermal image with a actual 8x8 resolution that is interpolated out to 24x24. A distance of device from user is recorded by a time of flight laser range finder. The distance is displayed with a color bar graph. A bar color of RED indicates the distance to user is beyond 50cm. A bar of GREEN indicates a distance of 50cm or less. The final BLUE bar indicates a distance of less than 25cm and invokes the EXG Sensor mode. An Object and Ambient temperature is displayed.
Fingerprint Mode
Placement of a finger on the fingerprint scanner activated this mode. Onscreen instructions direct the user to place finger an scanner. This suspends the Passive Mode. The onscreen instructions tell the user to keep finger on scanner until a fingerprint image is captured and displayed on the screen. When the scanner ring is pulsing RED, a fingerprint is not displayed. A GREEN ring indicates a fingerprint image has been captured and is being displayed. Upon removal of finger from scanner, the device returns to Passive Mode.
Pulse Mode
Placement of a finger on the pulse sensor activates this mode. This suspends the Passive Mode. The sensor reads the pulse and provides a beat indicator as well as an estimate pulse rate. Future upgrades will display the O2 Saturation level (stray diagnosis number under pulse rate). Upon removal of finger from sensor, the device returns to Passive Mode.
EKG Mode
When the device distance is met, or a finger is placed on the distance sensor, the EXG Mode is engaged. This suspends the Passive Mode. The entire screen is cleared and converted to display ~152 readings with automatic scaling to screen. If the distance reading remains in this modes range, additional readings are made and displayed until distance criteria changes. Upon mode change, the entire screen is redrawn and the fingerprint information is reset to not recorded. (Finger is over distance sensor, readings are from the BioAmp EXG Pill in a black box)

Tests

Test
Configuration Procedure
Eye Test
  • Only Base Device needed.

Instructions for the one being tested are displayed on the unit's screen. The one tested will be shown an "E" symbol of various sizes and orientations. The display will be activated based on distance readings from the Base Device distance sensor. After the display distance and time are met, the one tested will use a Rotary Encoder and Switch function, on the Control Panel, to select orientation on the "E" symbol. The process will be repeated with success or failure counts by orientation and distance will be recorded.

Hearing Test
  • Test requires earphones or headphones be plugged into Audio/MIDI shield audio jack.
  • Test can use either one or two Hand Held Units or use use the switch function of the Rotary Encoders on the Control Panel.

Instructions for the one being tested are displayed on the unit's screen. A series of tones of various frequencies and volumes are played to each ear in variable patterns. Upon detection of the Tone, the tested is required to signal detection by depressing the appropriate Hand Held Unit Button of Rotary Encoder. Tones are tested for a determined time and a timeout condition is considered to be non-detection. Repeat of the "missed" Tones can be retested for confirmation.

Grip and Reflex Test
  • Test can use of one or two Hand Held Units.

Instructions for the one being tested are displayed on the unit's screen. The one tested will be asked to grip the Hand Held Units multiple times to set a baseline for grip pressure readings for each Unit used. The one tested will then be required to register detection of the Units vibrating motor. The operating time of the motor will be varied. Detection of the vibration and time to detection are recorded. Detection will be based on grip detection and Unit Button depression as instructed during test.

EKG and Respiration Test A
  • Test requires EKG-Respiration Unit.

Instructions for the one being tested are displayed on the unit's screen. The victim/one tested will be appropriately "Wired Up" to the device. The sensor readings will be displayed to screen. If the one tested has a pulse and breathing is detected, the the one tested will be considered "NOT DEAD". If (a pulse but not breathing) or (breathing but no pulse) is detected the the one tested will be considered "NOT QUITE DEAD". If neither pulse or breathing is detected then the one tested could simply be "PINING FOR THE FJORDS" or "NOT ALIVE" but no assertion will be made as to their death.

EKG and Respiration Test B
  • Test requires EKG-Respiration Unit.

Instructions for the one being tested are displayed on the unit's screen. The victim/one tested will be appropriately "Wired Up" to the device. The sensor readings will be displayed to screen. Regardless of the sensor readings, the NeoPixel Unit on the EKG Unit will be cycled through various colors, brightness and/or sequences. Changes to sensor readings will then be wrecklessly assigned to conjecture as well as confession through projection interpretations.

EEG Test
  • Test requires EEG Unit.

Instructions for the one being tested are displayed on the unit's screen. The victim/one tested will be appropriately "Wired Up" to the device. The sensor readings will be displayed to screen. Regardless of the sensor readings, the NeoPixel Unit on the EEG Unit will be cycled through various colors, brightness and/or sequences. Changes to sensor readings will then be wrecklessly assigned to conjecture as well as confession through projection interpretations. This is a test of higher validity due to there being more lines displayed on the screen then the EKG and Respiration Tests.

Poly-Liar Test
  • Test requires EKG and Respiration Unit.
  • Test requires Poly-Liar Unit.

Instructions for the one being tested are displayed on the unit's screen. The victim/one tested will be appropriately "Wired Up" to the device. The sensor readings will be displayed to screen. After a series of harmless questions are asked and answered, the one tested will be subjected to scandalous and salacious questions and accusations. Every sensor change or stable reading will be left to predefined biased impressions and be held against the tested one's integrity. A Tone device may sound at random causing reading changes. These changes can be ignored or used as grounds to doubt the veracity of answers given.

Eye Tracking Analyzer Test A
  • Test requires Eye Tracking Unit.

Instructions for the one being tested are displayed on the unit's screen. The one being tested is warned, discouraged and berated to NOT take this test. Eye Safety has NOT BEEN ESTABLISHED.

Eye Tracking Analyzer Test B
  • Test requires Eye Tracking Unit.

Instructions for the one being tested are displayed on the unit's screen. The one being tested is asked to track a moving object with their eyes only. Movement of the head is tracked via the goggle's MPU. The ability of the tested one to hold head still is rated. Eye Safety has NOT BEEN ESTABLISHED.
