The phrase "ad hoc device" is correct and usable in written English.
It can be used to refer to a device or solution that is created for a specific purpose or situation, often in a temporary or improvised manner.
Example: "The team developed an ad hoc device to address the immediate technical challenges they faced during the project."
Alternatives: "temporary solution" or "makeshift tool".
The penetration force for each dilator was measured by using an ad hoc device.
A feature set is obtained from the processing of the ultrasonic signal that is recorded in through-transmission mode using an ad hoc device.
The paper argues that these sorts of "random walk" explorations could provide the basis for network communication algorithms used to estimate everything from social to ad hoc device networks, determining data when random sampling isn't available for various reasons.
We propose that thymic electroporation represents an interesting method for immunodeficiency gene therapy, which evidently requires optimization for clinical application, such as a systematic study to identify the optimal electropulsing sequence, injection periodicity and the ad hoc device for human electro-gene transfer.
We note that the causal role concept may sometimes be useful; mostly as an ad hoc device for traits whose evolutionary history and underlying biology are obscure.
PUs have the rights of accessing the licensed bands for communications with the primary BS, while SUs can only opportunistically access the sub-channels for ad hoc device-to-device transmissions.
In our model the devices could leave the network voluntarily or because of energy constraints, so we will not take into account the energy of the devices in our analytical model because the spontaneous network may be disappear before the energy of the ad hoc devices is consumed.
What appealed to them in Copernicus' model was its ability to do away with ad hoc devices in Ptolemy's system (such as the equant), to explain key phenomena in a pleasing fashion (the observed retrograde motion of the planets), and to explain away otherwise inexplicable coincidences in Ptolemy's system (such as the alignment of the Sun and the centres of the epicycles of the inferior planets).
Recent research efforts have been spent to develop ad hoc devices for the rapid one-step isolation of the SVF from liposuctioned adipose tissue to be grafted without prior ex vivo culture amplification manipulation [ 156].
Go Green Home Stores is working on bringing biodiesel brewers to its stores, making it so that folks don't have to create their own ad-hoc device.
The second is an "ad hoc" mechatronic device able to simulate some controls with rotary motions (knobs).
