Certain examples described herein relate to the use of three-dimensional threshold matrices in the production of three-dimensional objects. In one case, data values for a three-dimensional matrix for use in halftoning are assigned based on a structural volume coverage representation. In certain described cases, the structural volume coverage representation defines a probabilistic distribution of at least two different structures available for the production of the three-dimensional object. A comparison is performed based on data values for the structural volume coverage representation. The output of the comparison is a data value to be assigned to the three-dimensional matrix. The resultant three-dimensional matrix is used in a halftoning operation to control a structure distribution in the three-dimensional object. |

Dynamic certificate generation on a certificate authority cloud
Techniques are disclosed for dynamically generating a digital certificate for a customer server. A customer server creates a certificate profile and receives an associated profile identifier from a certificate authority (CA).

The agent application sends a signed request to the CA that includes the profile identifier, server identifier, and the public key corresponding to the key pair. Upon receiving the credentials, the CA generates a dynamically updatable certificate. Thereafter, if the customer changes information associated with the certificate (or if external conditions require a change to the certificate, such as a key compromise or change in security standards), the CA may generate an updated certificate based on the certificate profile changes and the public key. |

Circuit module
In a circuit module, even if a transmission signal output from a transmission electrode of a mounting substrate to a transmission terminal of a splitter leaks into a ground electrode, the transmission signal that has leaked into the ground electrode is mainly transmitted along an edge of the ground electrode and the transmission signal that has leaked into the ground electrode flows into a plurality of via conductors arranged with end surfaces superposed with the edge of the ground electrode when viewed in plan.

Frequency detection to perform adaptive peak current control
The amount of power being output to the load is sensed by sampling the frequency of the pulse width modulation signal that is controlling the switch that is providing the power to the load. If the pulse width modulation signal has a high frequency, then it will be providing higher power to the load. As the power drawn by the load decreases, the frequency of the pulse width modulation power supply signal will decrease. By sensing and periodically sampling the frequency of the pulse width modulation signal that is providing power, the demand of the load can be quickly and accurately determined. As the power demand of the load decreases, the peak current that the power supply switch can provide also decreases. The permitted peak current dynamically changes to adapt to the power drawn by the load. |
