Abstract: Systems and a method determine an amount of printing material powder for 3D printing an object a multi-object printing job. Data on the following is received: a 3D-model of the object, a volume and a surface of the object, data on a thickness of a powder, on characteristics of the build chamber, a volume of a no build zone and a volume of a net build zone, an estimation of a volume of recyclable interstitial powder, on a powder density and on a solid density of the printing material and on a recycling ratio. The following quantities are determined: a volume of the powder layer around the object, a dilated object contribution, the amount of used powder due the dilated object, the amount of lost powder in the no build zone, the amount of lost powder in the net build zone and the amount of printing material required.

Abstract: A method for training a subject diagnosed with a stress disorder caused by a trauma, including: selecting a challenge expected to trigger a symptom of the stress disorder in the subject; exposing the subject to the challenge; recording electrical signals generated by the brain of the subject by at least one electrode, in conjunction with the exposing; processing the recorded electrical signals to estimate an activation level of at least one specific brain region; presenting at least one indication of the estimated activation level to the subject; repeating the recording, the processing and the presenting.

Abstract: A method for resilience training, including: exposing a healthy human subject to one or more stress-evoking perturbations selected to affect activation of deeply located limbic areas; instructing the healthy human subject to perform in a timed relation to the exposing, at least one activity configured to selectively affect activation of said deeply located limbic areas; recording EEG signals from the healthy human subject during the exposing; analyzing the recorded EEG signals to identify at least one EEG signature indicating an activation level of the deeply located limbic areas; determining an activation level of the deeply located limbic areas based on the identified at least one EEG signature; delivering a human-detectable indication to the healthy human subject according to the determined activation level.

Abstract: A method for modifying the effect of a drug by application of an activation protocol, comprising: administering a drug according to a treatment protocol; applying an activation protocol in a timed relationship to the administering, for differentially activation of at least one selected brain region; wherein the differentially activation allows the drug to selectively interact with the at least one selected brain region.

Abstract: A quick release mechanism including a shaft having a first end cap and a second end cap is provided. The second end cap is attached to, or associated with, a lever designed and configured for actuating the quick release mechanism between closed and open positions and for use as a bicycle repair tool.
