Abstract: A projector can include a housing, a light source, a first achromatic doublet, and a second achromatic doublet. The light source can provide a light beam and positioned at a first position within the housing. The first achromatic doublet can be positioned at a second position within the housing. The second achromatic doublet can be positioned at a third position within the housing. The second position can be between the first position and the third position. The housing can include a slot to receive a slide including a graphical image. The slot can receive the slide located between the first position and the second position and at a defined distance from the first achromatic doublet. The defined distance can be dependent on focal lengths of the first achromatic doublet and the second achromatic doublet and a distance between the first achromatic doublet and the second achromatic doublet.

Abstract: The present invention is concerned with novel CRISPR-Cas systems which are configured to detect the presence of a target nucleic acid in a sample through activation of secondary nucleases which bind and cleave a nucleic acid probe modified with a (e.g.) fluorophore/quencher moieties, where a change in the property of the probe (e.g. modified fluorescence) reflects the presence of the target nucleic acid in a sample to be tested.

Abstract: A wearable posture monitoring device is provided. The device includes a first posture sensor to measure a first bend parameter associated with shoulders of a user and a second posture sensor to measure a second bend parameter associated with vertebral column of the user. The device includes a control unit operatively coupled to the first posture sensor and the second posture sensor and is configured to compare the first bend parameter with a first predefined reference value and the second bend parameter with a second predefined reference value to detect an improper bend in one or more of the shoulders and vertebral column of the user. The control unit is further configured to display a visual indication, on a display interface associated with the posture monitoring device, to indicate the detected improper bend of one or more of the shoulders and vertebral column of the user.
