Abstract:
The present invention is a mobile microscopy device, that can be integrated onto mobile imaging devices and mobile phones (15), and take images in different wavelengths to be used in various fields where microscopic investigation is needed, characterized in that; it comprises a lens module (12), being placed into an imaging head (11) and having at least one lens that carries out different magnification rates as needed, a filter module (13) having at least one filter device to filler out reflected light being sent in different wavelengths so as to be sensed by the imaging sensors, a led module (14) having at least one led to send light beams in different wavelengths.
Abstract:
A smartphone is adapted for use as an imaging spectrometer, by synchronized pulsing of different LED light sources as different image frames are captured by the phone's CMOS image sensor. A particular implementation employs the CIE color matching functions, and/or their orthogonally transformed functions, to enable direct chromaticity capture. A great variety of other features and arrangements are also detailed.
Abstract:
In one or more implementations, a temperature measuring system is provided, including a temperature sensing probe having (a) a thermistor operatively connected to a first conductor and (b) a resistor operatively connected to a second conductor, and a temperature determination application stored in a memory of a computing device operatively connected to the temperature sensing probe. When executed by a processor of the computing device, the temperature determination application configures the computing device to: transmit a first instance of a signal to the first conductor, receive a temperature signal from the thermistor, the temperature signal corresponding to the first instance of the signal as output from the thermistor, transmit a second instance of the signal to the second conductor, receive a reference signal from the resistor, the reference signal corresponding to the second instance of the signal as output from the resistor, process the temperature signal and the reference signal to determine a relationship between the temperature signal and the reference signal, and compute a temperature based on the relationship.
Abstract:
A mobile system for analyzing ECG data includes an analog front end module coupled to a mobile consumer device. The analog front end module is configured to collect ECG data from one or more leads and is operable to convert the analog ECG data to digital ECG data. The mobile consumer device, such as a smart phone (400), is coupled to receive the digital ECG data (150), and is configured to perform QRS detection (451 ) using a filter (436) whose cutoff frequency is adapted to noise level in real time. The ECG signal is amplified non-linearly (431 ) and three windowed threshold signals (D, E, J) are derived. The cutoff frequency for the QRS detection is dynamically selected (439) as a function of the threshold signals. A sample in the amplified signal is identified to be a heart beat point only when the sample value is equal to the first threshold signal and greater than the filtered threshold signal.
Abstract:
A sleep sensing system comprising a sensor to obtain real-time information about a user, a sleep state logic to determine the user's current sleep state based on the real-time information. The system further comprising a sleep stage selector to select an optimal next sleep state for the user, and a sound output system to output sounds to guide the user from the current sleep state to the optimal next sleep state.
Abstract:
Location tracking is used to monitor or diagnose clinical conditions in patients to promote accurate reporting of patients' whereabouts and activity levels. Changes in movement patterns allow for detection and monitoring of diseases and clinical conditions. Patients may choose their desired privacy level, as well as the locations which they wish to track. Embodiments of this invention allow patients the option to set their personal information as anonymous.
